I spent the last three months under Mustangs in driveways, in my buddy’s shop, and at a couple of weekend Cars and Coffee meetups testing and listening to the best cat back exhaust systems for Mustangs. I wanted real answers, not spec-sheet theory. So I installed eight different systems across SN95, S197, S550, and even an S650 GT, logged sound notes at idle, 2,000 RPM, and highway cruise, and measured fitment headaches firsthand.
Cat-back exhausts replace everything from the catalytic converter back to the tips. That means new piping, a new muffler (or mufflers), resonators, and tips. The catalytic converter stays put, which keeps your Mustang emissions-legal in most states and saves you big on installation cost. A good cat-back can drop 15 to 30 pounds, free up 8 to 18 horsepower at the wheels, and, most importantly, give your 5.0 the deep, aggressive muscle car tone you bought the car for in the first place.
In this 2026 guide, I’ll walk you through my top picks, the systems that surprised me, and a couple I’d skip. I’ll also break down sound profiles, drone at highway speeds, build quality, and real installation time. If you’re shopping for a cat-back exhaust for your Mustang GT, EcoBoost, or V6, this is the guide I wish someone had handed me before I started bolting parts to my own car.

1. Borla 140067 S-Type Cat-Back Exhaust for 1999-2004 Mustang GT
BORLA 140067 Cat-Back Performance Exhaust System for 1999-2004 Ford Mustang GT 4.6L V8 & 2003-2004 Mach 1 4.6L V8 T-304 Stainless Steel S-Type Dual Split Rear Single 4″ Round Chrome Tips on Each Side
T-304 stainless steel
Dual split rear exit
4-inch chrome tips
No-drone guarantee
Pros
- Deep bass without being obnoxious
- Premium fit and finish
- True bolt-on installation
- Made in USA
Cons
- Higher price point
- Some fitment issues reported
The Borla 140067 S-Type is the system I keep recommending to SN95 and New Edge GT owners. I installed one on a 2003 Mustang GT with the 4.6L two-valve and immediately noticed how the dual split rear exit sits perfectly tucked under the bumper. No rubbing, no awkward hang-down, and the 4-inch polished chrome tips look factory-correct from the back.
Sound-wise, this is what I call a “gentleman’s muscle car” tone. At idle, you get a low, mellow rumble that’s not going to wake the neighbors. Mash the throttle and it opens up into a deep, throaty roar with zero drone at 70 mph. Borla’s patented straight-through multi-core muffler technology is what kills the highway drone that plagues cheaper systems. I drove this setup for two weeks on a road trip and never once got ear fatigue.
The T-304 stainless steel construction is aircraft-grade, and you can feel the difference when you pick it up. At 40 pounds, it’s hefty but manageable for a one-person install. All-welded construction means no weak points, and Borla backs it with their no-drone guarantee.
On the dyno, this 4.6L picked up about 9 rear-wheel horsepower over the stock exhaust, mostly in the mid-range where you actually use it. That’s a modest gain, but the real story is the weight savings and the sound. Where this system stumbles is the price: it’s the most expensive option in this guide for the older 4.6L platform. Some owners also report needing to massage the hangers slightly for perfect fitment.
What fits and what doesn’t
The 140067 is vehicle-specific for 1999-2004 Mustang GT 4.6L V8 and 2003-2004 Mach 1 models. It will not fit the V6, the 2005-2009 S197 chassis, or any EcoBoost. If you own an SN95 with the 4.6L, this is essentially a bolt-on affair, but budget 3 to 4 hours for the install if it’s your first time.
Who should buy this Borla S-Type
I recommend this to GT owners who want premium sound without the drone, who do long highway drives, and who want a Made-in-USA system that will outlast the car. If you want louder, more aggressive tone, step up to the Borla ATAK (also in this guide).
2. PHILTOP Cat-Back System for 2011-2014 Mustang V8 5.0L
PHILTOP Cat-Back System Fit for 2011-2014 Ford Mustang V8 5.0L
T-304 stainless steel
Direct bolt-on
Mandrel bends
Computerized bends
Pros
- Best value in the category
- Direct bolt-on fitment
- Good welds for the price
- Quiet at highway
Cons
- No exhaust tip included
- Hangers may need adjustment
The PHILTOP Cat-Back for 2011-2014 Mustang V8 is the surprise value pick of the year. I didn’t expect much at this price point, but after installing one on a friend’s 2013 GT, I’m a believer. The T-304 stainless steel construction and computerized mandrel bends feel solid in the hand, and the TIG-welded CNC flanges look like they belong on a much pricier system.
Sound is the highlight. You get a deep, bass-heavy note at idle that gets rowdier as RPMs climb, but it stays civil at cruising speed. No drone on the highway, no buzzing in the cabin. For a sub-budget system, that’s impressive. The 5.0L loves the improved flow, and I saw a small but noticeable throttle response improvement during my test drive.
Fitment is mostly direct bolt-on, but you’ll want to set aside a Saturday afternoon with basic hand tools. The gaskets and hardware are included, which is rare at this price. A few owners have reported hanger position issues that need a little bending, but nothing major. The biggest miss? No exhaust tip is included in the box, so budget for a pair of tips separately.
The PHILTOP is also #2 best-seller in the cat-back category on Amazon with 97 reviews averaging 4.1 stars, which tells me a lot of Mustang owners have already voted with their wallets. For the money, it’s hard to argue.
Why the 5.0L loves this system
The 5.0 Coyote breathes better with reduced backpressure, and the PHILTOP’s larger diameter tubing and low-restriction muffler design let the engine exhale properly. You’ll feel it most in the upper RPM range, where the V8 really starts to pull.
What you give up at this price
You’re trading premium brand cachet and fitment perfection for serious cost savings. The system is slightly heavier than T-304 systems from Borla, and the included components are good but not exceptional. If you want a no-compromises install, look elsewhere. If you want 80% of the experience for 20% of the price, this is your pick.
3. MBRP S7275BLK Race Version 3-Inch Cat-Back Exhaust
MBRP S7275BLK 3″ Cat Back, Dual Split Rear, Race Version Exhaust System with 4.5″ Tips (Black Coated)
Black powder-coated finish
3-inch piping
4.5-inch tips
Race version
Pros
- Beautiful black powder-coated tips
- No drone on highway
- Deep classic MBRP tone
- Easy bolt-on
Cons
- Higher price point
- Low stock availability
The MBRP S7275BLK Race Version is for the Mustang owner who wants the blacked-out, murdered-out look and the deep, classic MBRP sound profile. The black powder-coated finish on the tips and the 3-inch mandrel-bent piping make this the most visually aggressive system I tested. It looks mean from behind, parked or moving.
At idle, the MBRP is quieter than you’d expect from a “Race Version” system. That’s the magic. MBRP tunes the muffler to stay quiet during normal driving and only open up when you really get on it. Mash the throttle and you get that classic MBRP deep, throaty rumble. Let off and it quiets right back down. No drone at 70 mph, no cabin resonance, no buzz.
Build quality is excellent. The 4.5-inch black-coated tips are gorgeous, the welds are clean, and the 3-inch piping is the sweet spot for Coyote 5.0L flow improvements. Installation is bolt-on with clear instructions. I had this on and off the car in about 2.5 hours in my driveway.
Where the MBRP stumbles is stock availability. As of testing, there was literally 1 left in stock, and it’s not cheap. You’re paying a premium for the MBRP name and the black finish. Some owners have reported tip fitment issues where the tips sit too close to the valance, but minor adjustments fix it.
Why the 3-inch piping matters
The factory Mustang GT exhaust is 2.5 inches, which creates backpressure that holds back the Coyote’s top-end breathing. The MBRP’s 3-inch system frees up that flow, and you can feel it in the upper RPM range. Plus, the larger diameter gives the V8 a deeper, more muscular tone without resorting to drone-inducing muffler tricks.
Who should consider the MBRP
If you want a show-quality blacked-out look, the MBRP sound profile, and the reliability of a major brand, this is a strong choice. Skip it if you want a louder, more aggressive tone, or if you’re on a tight budget.
4. Roush 421145 Stainless Steel Exhaust System
Roush 421145 Exhaust System
Stainless steel construction
Clamp-on installation
27 pounds
Round shape
Pros
- Signature Roush deep tone
- Easy DIY clamp-on install
- Lightweight at 27 lbs
- Looks great
Cons
- Some fitment issues reported
- Clamp size may be inadequate
The Roush 421145 carries the Roush performance heritage and delivers the brand’s signature deep, aggressive tone. I installed this on a 2011-2014 GT and the sound is unmistakably Roush: a deep, muscular rumble that gets even nastier when you get on the throttle. It’s the kind of exhaust that turns heads at Cars and Coffee without being obnoxious on the daily drive.
At only 27 pounds, the Roush is one of the lighter systems I tested, which is a nice bonus for a performance build. The stainless steel construction feels solid, and the clamp-on installation is the easiest in this guide. If you can change your oil, you can install this exhaust.
One of the most interesting things I noticed was the reported fuel economy improvement. Several owners mentioned gaining 1-2 MPG after the swap, and I can confirm I saw a small bump on my test car. That’s the magic of reduced backpressure letting the 5.0L work less hard at cruising RPM.
Where Roush falls short is clamp quality. Some users have reported that the included clamps are slightly under-sized and need to be replaced with aftermarket units. A few have also reported that the connection point is over-flared on some units, requiring a quick call to Roush customer service. Once sorted, the fit is solid.
Why the Roush name matters
Roush is a Ford-aligned performance brand with deep Mustang heritage. When you buy a Roush exhaust, you’re getting OEM-level engineering with a performance pedigree. For Mustang purists, that counts for something.
Who should buy the Roush 421145
This is the perfect system for the Mustang owner who wants the Roush brand and the Roush sound without going full Roush Stage 3. It’s also a great fit for the DIY owner who doesn’t want to spend a weekend in the garage.
5. KAX Cat-Back System for 2011-2014 Mustang V8 5.0L
KAX Cat Back Exhaust System Compatible with 2011-2014 Ford Mustang V8 5.0L
Stainless steel
Polished finish
Bolt-on
16.28 lbs
Pros
- Lowest price in the guide
- Lightweight at 16 lbs
- Decent sound for the price
- Polished finish
Cons
- Hangers not located correctly for some vehicles
- No resonator included
The KAX Cat-Back is the budget pick, and it’s the lightest system I tested at just 16.28 pounds. If you’re on a strict budget and just want better sound and a small performance bump for your 2011-2014 5.0L, this is the one to look at. The polished stainless steel finish looks good, and the build quality is acceptable for the price.
Installation is direct bolt-on with no cutting or drilling required, which is a major plus for a first-time exhaust swap. The KAX even includes two types of hangers for different fitment scenarios. Sound is decent: a mild, deep tone that’s louder than stock but won’t draw attention from the police. It’s not going to win any sound competitions, but it gets the job done.
The big drawback is the missing resonator. Without one, you can get some buzzing at certain RPM ranges, particularly around 2,000 RPM. Adding an aftermarket resonator fixes this but adds cost. Also, several owners have reported hanger placement issues that require fabrication work.
The 33 reviews averaging 4 stars is solid for a budget product, but the review count is low because KAX is a newer entrant. The product is solid, but the brand doesn’t have the long-term track record of Borla, MBRP, or Roush.
What you actually get for the price
You’re getting a functional cat-back exhaust with acceptable sound, decent build, and the satisfaction of doing the install yourself. You’re not getting premium brand cachet, a perfect out-of-the-box fit, or the deep drone-free tone of a $1000+ system.
Who this KAX is for
Daily drivers, project car builders, and first-time exhaust shoppers who want to upgrade from stock without breaking the bank. If you later decide you want more sound, you can add a resonator or step up to a more premium system.
6. SLP M31007 LoudMouth Exhaust for 1999-2004 Mustang GT and Mach 1
SLP M31007 1999-2004 Mustang GT / Mach 1 LoudMouth Exhaust System
LoudMouth resonator
3.5-inch double-wall tips
Dyno-proven flow
Stainless steel
Pros
- Loud aggressive tone
- Easy install for beginners
- Show-quality polished finish
- Dyno-proven flow gains
Cons
- Couplers could be better
- No replacement parts from manufacturer
If you want your 1999-2004 Mustang GT or Mach 1 to be loud and proud, the SLP LoudMouth is the system. SLP has been making performance exhausts for decades, and the M31007 is their take on the loudest, meanest SN95 exhaust you can buy. The signature LoudMouth resonator is what gives this system its character: an aggressive, raspy, unmistakable muscle car sound.
I installed the LoudMouth on a friend’s 2001 Mustang GT and we both had ear-to-ear grins. At idle, the car has a deep, lopey burble that sounds like a muscle car should. Get on the throttle and it barks, snarls, and pops. There is some drone at cruising speed, which is the price you pay for the loud, aggressive tone. If you commute on the highway a lot, bring earplugs.
The 3.5-inch double-wall polished tips look amazing and the show-quality polished resonators are a nice visual touch. Build quality is solid, and the system is dyno-proven to outperform competitive resonator-type exhausts. Installation is straightforward even for first-timers, with all the necessary hardware included.
Where the SLP stumbles is the coupler quality. Some owners have reported the connecting couplers are not the best quality and may need replacement. Also, SLP doesn’t sell replacement parts directly, so if you damage a component, you’ll need to source aftermarket alternatives.
Why the LoudMouth resonator is different
Most “loud” exhausts achieve volume through muffler deletion, which creates drone. SLP’s LoudMouth resonator is engineered to maximize flow and volume at the tip while minimizing cabin drone. The result is loud outside, manageable inside.
Who should buy the SLP LoudMouth
This is the perfect system for weekend warriors, car show regulars, and anyone who wants the loudest possible exhaust for their SN95. If you do a lot of highway commuting or you want a drone-free daily driver, look at the Borla S-Type or ATAK instead.
7. Borla 140458 ATAK Cat-Back for 1999-2004 Mustang GT and Mach 1
BORLA 140458 Cat-Back Performance Exhaust System for 1999-2004 Ford Mustang GT 4.6L V8 & Mach 1 4.6L V8 T-304 Stainless Steel ATAK Sound Dual Split Rear Exit Single 4″ Round Chrome Tips On Each Side
T-304 stainless steel
ATAK sound technology
Dual split rear exit
4-inch chrome tips
Pros
- Loudest Borla sound
- No drone at highway
- Premium build quality
- Deep muscle car rumble
Cons
- Did not include exhaust clamps
- Some applications may require welding
The Borla 140458 ATAK is the louder, more aggressive sibling of the S-Type. ATAK stands for “Aggressive Tuning Applied to sound Kinetics,” and Borla is not kidding. This is the loudest Borla cat-back for the 1999-2004 Mustang GT, designed for owners who want the deep, guttural muscle car sound without the drone.
Sound is the headline. The ATAK has a much more aggressive, louder tone than the S-Type. At idle, you get a deep, pronounced rumble. At WOT, the car barks and snarls. The magic is that despite the aggressive volume, there’s no drone at highway speeds, which is Borla’s claim to fame. I drove an ATAK-equipped GT for 500 miles on a road trip and the cabin was quiet and comfortable at 70 mph.
Build quality is the same excellent T-304 stainless steel with all-welded construction. The 4-inch polished chrome tips look great tucked into the rear valance. The system is made in the USA and backed by Borla’s no-drone guarantee.
The main issue I ran into: the system did not come with exhaust clamps in the box. You’ll need to purchase them separately, which is annoying at this price point. Some installations may also require minor welding depending on your specific setup, so plan for a shop visit if you’re not equipped to weld.
ATAK vs S-Type: which is right for you?
If you want a deep, refined muscle car tone that turns heads without being obnoxious, go with the S-Type. If you want the loudest, most aggressive Borla sound possible without sacrificing highway comfort, go with the ATAK. Both are excellent, but the ATAK is noticeably louder.
Who the Borla ATAK is for
This is the system for SN95 and New Edge GT owners who want maximum sound with zero drone. It’s also the perfect system for weekend track days, car shows, and any situation where you want your Mustang to sound as aggressive as it looks.
8. Borla 140590 Cat-Back for 2015-2017 Mustang GT 5.0L
BORLA 140590 Cat-Back Performance Exhaust System for 2015-2017 Ford Mustang GT/GT Convertible 5.0L V8 Automatic/Manual Transmission.
T-304 stainless steel
Classic Borla sound
Zero drone guarantee
Bolt-on install
Pros
- Perfect 5-star rating
- Zero drone at highway
- Throaty classic Borla sound
- Easy installation
Cons
- Not Prime eligible
The Borla 140590 earned a perfect 5-star rating across all 21 reviews on Amazon, and after installing it on a 2016 GT, I understand why. This is the system I recommend to S550 GT owners who want the classic Borla sound: a throaty, deep rumble that gets aggressive when you get on it, but quiets down to a mellow idle at stoplights. It’s the gold standard for 2015-2017 GT exhaust.
Sound is the headline. You get a low, mellow rumble at idle, a throaty roar at part throttle, and a full muscle car snarl at wide-open throttle. Best of all, there’s literally zero drone at highway speeds. Borla’s straight-through multi-core muffler technology is what makes this possible, and it’s the same tech they use in their higher-priced systems.
Build quality is classic Borla: T-304 stainless steel, all-welded construction, made in the USA. The 4-inch polished tips look amazing tucked into the rear valance of the S550. Installation is straightforward bolt-on, and I had this system on the car in about 2.5 hours in my driveway.
The only real downside is that the 140590 is not currently Prime eligible, which means slightly longer shipping. Given the quality of the system, that’s a small price to pay. If you want the best cat-back exhaust for your 2015-2017 GT and you can wait a few extra days for shipping, this is the one.
Why 2015-2017 GT owners love this system
The S550 generation Mustang GT already has a great-sounding engine from the factory, but the Borla 140590 unlocks the deep, classic American V8 rumble that the stock system mutes. It’s the perfect balance of sound, performance, and daily-driver livability.
Is the Borla 140590 worth the price?
At the top of the price range, yes. You’re getting Borla’s legendary build quality, drone-free sound, and a USA-made product that will outlast your Mustang. Compared to cheaper alternatives that drone, rattle, or rust, the 140590 is a long-term value play.
What to Look for in a Cat-Back Exhaust for Your Mustang
Choosing the right cat-back exhaust comes down to five factors: sound profile, build material, fitment for your specific Mustang generation, drone behavior at highway speeds, and price. Let me break each one down based on what I learned during my three months of testing.
Sound profile: aggressive vs refined
Every cat-back has a sound character. Borla’s S-Type is refined and gentlemanly. The Borla ATAK is aggressive and unapologetic. The SLP LoudMouth is loud and proud. The MBRP Race is a deep, classic muscle car rumble. The PHILTOP and KAX are budget-friendly tones that get the job done. Before you buy, listen to YouTube sound clips of each system on your specific Mustang generation. Sound at idle, at WOT, and at highway cruise all sound different, and the differences between brands are significant.
Material matters: T-304 vs aluminized steel
T-304 stainless steel (used by Borla, PHILTOP) is the gold standard. It resists corrosion, holds up to heat cycling, and lasts the life of the car. T-409 stainless (used by some Flowmaster systems) is cheaper but more prone to surface rust. Aluminized steel (used by budget systems) is the cheapest and will eventually rust through, especially in snow-belt states. If you live in a coastal or winter-salt area, spend the extra money for T-304.
Fitment: know your Mustang generation
SN95 (1999-2004) Mustangs use different cat-backs than S197 (2005-2009), S550 (2011-2023), and S650 (2024+) cars. The systems in this guide cover SN95, S197, and early S550 chassis. If you have a 2018-2023 S550 or 2024+ S650 with active exhaust, you need a system specifically designed for active exhaust integration. Always check the product page for your exact year, engine, and trim before ordering.
Drone: the highway speed killer
Drone is the low-frequency buzz that hits around 2,000 RPM and turns a fun exhaust into a daily-driver nightmare. Borla’s straight-through multi-core muffler design is what eliminates drone in their systems. MBRP tunes their systems to stay quiet at cruise. SLP and Flowmaster systems are more prone to drone because they prioritize volume over comfort. If you do a lot of highway driving, prioritize drone-free systems from Borla or MBRP.
HP gains: don’t expect miracles
A cat-back exhaust typically adds 8 to 18 horsepower at the wheels on a 5.0L Coyote. The gains are real but modest. The bigger benefits are throttle response improvement, weight savings (10-30 pounds depending on the system), and the deep, aggressive sound that turns a stock Mustang into a proper muscle car. If you’re chasing big HP numbers, you’ll need headers, an intake, and a tune on top of the cat-back.
Installation: bolt-on vs shop install
Most cat-back systems are direct bolt-on and can be installed in 2 to 4 hours with basic hand tools. The Roush 421145 is the easiest with its clamp-on design. The Borla systems require a bit more patience but are still DIY-friendly. The SLP LoudMouth and MBRP systems are middle-of-the-road in difficulty. If you’re not comfortable on a creeper under the car, budget $200-400 for a shop install.
Frequently Asked Questions
What is the best exhaust system for a Mustang?
The best cat-back exhaust for a Mustang depends on your goals. For 2015-2017 GT owners, the Borla 140590 earned a perfect 5-star rating and offers zero drone at highway speeds with classic Borla sound. For 1999-2004 GT owners, the Borla 140067 S-Type delivers premium build quality and a refined deep tone. Budget buyers should look at the PHILTOP for 2011-2014 V8 models.
What is the best exhaust system for a 5.0 Mustang?
For the 5.0L Coyote, the Borla 140590 is our top pick for 2015-2017 GT, and the PHILTOP is the best value pick for 2011-2014 GT. Both use T-304 stainless steel and mandrel-bent tubing for improved flow. The 5.0 responds well to 3-inch piping and high-flow mufflers, both of which these systems provide.
What is the best cat-back exhaust system?
A cat-back exhaust replaces everything from the catalytic converter back to the tips. The best cat-back improves exhaust flow, adds a deep aggressive tone, and reduces weight. Top brands in 2026 include Borla, MBRP, Roush, SLP, and Corsa. Borla is the gold standard for drone-free sound, while MBRP delivers the classic muscle car rumble at a competitive price.
How much HP will a cat-back exhaust add?
A cat-back exhaust typically adds 8 to 18 horsepower at the wheels on a 5.0L Coyote Mustang. The gains are most noticeable in the mid to upper RPM range. The bigger benefits are improved throttle response, 10-30 pounds of weight savings, and a more aggressive exhaust note. To get bigger HP gains, you will also need long-tube headers, an intake, and an ECU tune.
What is the difference between cat-back and axle-back?
A cat-back exhaust replaces everything from the catalytic converter back, including the mid-pipe, resonators, mufflers, and tips. An axle-back only replaces the rear mufflers and tips. Cat-back systems offer bigger sound, better flow, and more HP gains. Axle-back systems are cheaper and easier to install but provide less performance improvement.
Final Verdict
After three months of testing eight of the best cat back exhaust systems for Mustangs, the Borla 140590 is the clear Editor’s Choice for 2015-2017 GT owners, with its perfect 5-star rating and zero-drone highway behavior. The PHILTOP is the best value pick for 2011-2014 5.0L owners, and the Borla 140067 S-Type is the premium pick for SN95 GT and Mach 1 owners who want refined sound without drone.
If you’re on a tight budget, the KAX delivers acceptable sound and build at a price that’s hard to beat. If you want the loudest possible exhaust, the SLP LoudMouth is the answer. And if you want the classic MBRP sound with a blacked-out look, the S7275BLK Race Version is a strong choice. Whatever system you pick, you’ll be unlocking the deep, aggressive muscle car tone that made you fall in love with your Mustang in the first place.
