Mustang GT Exhaust: Borla & Corsa Cat-Back Picks

If you drive a Mustang GT, the right exhaust can change how the car feels every time you start it. A good system can add a deeper V8 tone, reduce unwanted highway drone, improve flow, and give the rear of the car a cleaner performance look.

This guide focuses on Mustang GT cat-back and axle-back exhaust systems that make sense for real buyers: daily drivers who want a richer sound, weekend drivers who want more aggression, and owners who need to match the exhaust to a specific Mustang generation before ordering.

Top Picks

How We Chose These Exhausts

You want an exhaust that sounds better than stock without becoming a problem on long drives. We prioritized Mustang-specific systems with strong fitment information, stainless construction, clear sound profiles, useful owner feedback, and practical installation paths.

We also separated cat-back and axle-back systems because they solve different problems. Cat-back systems usually make the bigger change to sound and flow, while axle-back systems are often the simpler way to change the rear muffler sound and appearance.

Borla S-Type Cat-Back 140590

If you want your 2015-2017 Mustang GT to sound more serious without making highway driving tiring, the Borla S-Type 140590 is the strongest all-around pick. It gives the 5.0L V8 a deeper rumble at idle and a stronger voice under throttle, while staying more controlled than the loudest race-style options.

The main appeal is balance. You get a cat-back layout, T-304 stainless construction, 4″ polished tips, and a sound profile that works for daily driving, weekend back roads, and meets. Convertible owners should still plan for extra install time because rear bracing can make removal and alignment more involved.

What People Say

Owner feedback commonly praises the deeper tone, clean build quality, and low-drone highway behavior. The most repeated caution is that convertible installation can take more effort than coupe installation.

Overall Sentiment: Positive

Situational Benefits

Problems It Solves

This system fixes the stock exhaust’s quiet, muted character while avoiding the biggest downside many buyers fear: constant drone. It is a strong choice if you want a performance sound upgrade that still feels livable.

Key Benefits

• Balanced S-Type sound for daily driving and spirited use
• Cat-back design for a bigger change than a muffler-only swap
• T-304 stainless construction for durability
• 4″ bright chrome tips for a clean rear finish
• Vehicle-specific fit for 2015-2017 Mustang GT models

Borla ATAK Cat-Back 140591BC

If you want your 2015-2017 Mustang GT to sound bold and modern, the Borla ATAK 140591BC is the louder choice. It keeps the cat-back layout and stainless build of the S-Type options, but the ATAK tuning is designed for a sharper, more aggressive exhaust note.

This is best for drivers who want the car to stand out during acceleration, cold starts, and meets. It is not the quietest pick here, so daily drivers should be honest about how much volume they want before choosing it.

What People Say

Buyer feedback tends to praise the wake-up effect, black chrome tip appearance, and lack of harsh cruise behavior for such an aggressive system. The main caution is simple: ATAK is meant to be louder than S-Type.

Overall Sentiment: Positive

Situational Benefits

Problems It Solves

This system solves the problem of a stock Mustang GT that sounds too restrained. It gives the car a more dramatic sound without moving into custom fabrication or off-road-style modifications.

Key Benefits

• ATAK tuning for a louder, more aggressive exhaust note
• Cat-back layout with connecting pipes, mufflers, and hardware
• T-304 stainless construction
• 4″ black chrome rolled tips

Corsa 14332BLK Cat-Back (Black Tip)

The Corsa 14332BLK is the pick for drivers who want strong sound when accelerating but do not want the cabin to boom on long highway drives. The listing copy highlights CORSA’s RSC technology, which is designed to manage drone while keeping the exhaust aggressive under load.

This makes it a practical choice for a Mustang that sees both weekday commuting and weekend fun. Before buying, confirm the fitment shown on the Amazon listing against your exact year and trim because exhaust compatibility is model-specific.

What People Say

Owner feedback focuses on the mix of aggressive sound and comfortable cruising. Buyers also tend to mention solid construction and a cleaner black-tip look.

Overall Sentiment: Positive

Situational Benefits

Problems It Solves

This system is aimed at the common Mustang buyer dilemma: you want a stronger exhaust note, but you do not want a constant booming cabin. It is best for drivers who want performance sound only when they ask for it.

• 304 stainless steel construction

Borla 11895 ATAK Axle-Back

The Borla 11895 is the simpler ATAK route for 2015-2017 Mustang GT owners. Because it is an axle-back system, it focuses on the rear muffler and tip section rather than replacing as much of the exhaust as a full cat-back.

Choose this if your main goal is a louder Borla ATAK character, easier installation, and a clean 4″ tip look. Skip it if you specifically want the larger system change of a full cat-back.

What People Say

Feedback commonly points to a stronger, deeper sound and sturdy construction. A few buyers mention needing light fitment adjustment, which is common enough with exhaust installs to plan for alignment time.

Overall Sentiment: Positive

Situational Benefits

Problems It Solves

This axle-back fixes the bland rear muffler sound of the stock system. It is a good fit if you want attitude and a cleaner tip finish without changing more exhaust than needed.

Key Benefits

• ATAK-tuned sound in an axle-back package
• T-304 stainless steel construction
• 4″ bright chrome tips
• Designed for 2015-2017 Mustang GT fitment

Borla 140590BC S-Type Cat-Back

The Borla 140590BC is the black chrome tip version of the balanced S-Type cat-back direction. It is not the ATAK axle-back option. It is a better match for drivers who want a refined, deeper sound and a darker rear-tip look.

For daily use, it sits in the sweet spot between stock quiet and full aggressive volume. It is especially useful if you want a full cat-back upgrade but do not want the loudest Borla sound profile.

What People Say

Owner feedback highlights the sound balance, clean fit, and quality feel. Buyers who prefer black exterior accents will likely find the black chrome tips more attractive than polished chrome tips.

Overall Sentiment: Positive

Situational Benefits

Problems It Solves

This system gives buyers a full cat-back upgrade without forcing them into the loudest sound category. It also solves a styling problem for owners who do not want bright chrome tips.

Key Benefits

• S-Type tone for a balanced street-friendly sound

• Black chrome 4″ tips
• Cat-back layout with connecting pipes and mufflers
• Fitment focus for 2015-2017 Mustang GT and GT Convertible models

FAQ

Which Exhaust Should I Choose For My Mustang GT?

Choose based on year fitment first, then sound level. For 2015-2017 GT owners, the Borla 140590 S-Type is the safest all-around pick for a deeper tone with street-friendly manners. Choose Borla ATAK if you want a louder and sharper sound. Choose Corsa if low-drone cruising is your top concern. For older Mustang GTs, use the product that matches your generation, such as the Borla 140067 for 1999-2004 cars or the Borla 140135 for 2005-2009 cars.

Cat-Back Vs Axle-Back: Which One Makes More Sense?

A cat-back system replaces more of the exhaust behind the catalytic converters, so it usually makes a bigger change to sound, flow, and appearance. An axle-back system changes the rear muffler and tip section, so it is often simpler and more focused on sound. If you want the larger upgrade, choose cat-back. If you want a simpler sound change, choose axle-back.

Will An Aftermarket Exhaust Cause Drone?

Drone depends on the exhaust design, car setup, speed, gearing, and cabin sensitivity. S-Type systems are usually chosen for a more balanced sound, ATAK systems are chosen for more aggression, and Corsa’s RSC design is aimed at reducing cruise drone. If you are sensitive to cabin noise, listen to sound clips from your exact Mustang year and transmission before ordering.

Will A Cat-Back Or Axle-Back Exhaust Affect Emissions?

Most cat-back and axle-back systems keep the catalytic converters in place, but rules vary by location. Always check local emissions and noise regulations before buying, and do not remove required emissions equipment for street use.

How Hard Is Installation?

Many systems are designed for bolt-on installation, but real-world difficulty depends on rust, access, body style, tools, and lift availability. Convertible Mustangs can require extra attention around bracing. Use penetrating oil on old hardware, support the exhaust safely, align the tips before final tightening, and recheck clamps after a few heat cycles.

Buyers Favorite Exhausts

When choosing between the Borla S-Type 140590, Borla ATAK 140591BC, and Corsa 14332BLK, buyers usually compare sound first. The S-Type is the balanced daily-friendly choice, the ATAK is the louder attention-getting choice, and the Corsa is the low-drone performance-focused choice. Fitment, tip finish, installation type, and tolerance for cabin noise should decide the final pick.

Wrapping Up

Choosing the right Mustang GT exhaust is about more than volume. Match the system to your exact model year, decide whether you want cat-back or axle-back, and be honest about how much sound you want every day. For most 2015-2017 GT owners, the BORLA 140590 S-Type is the best balanced pick. For louder sound, the BORLA ATAK options make more sense. For highway comfort with performance sound, the Corsa 14332BLK is the low-drone option to compare closely.
