The 2024+ Ford Mustang S650 has officially claimed its throne as the last standing American V8 muscle car. But while the 5.0L Coyote engine under the hood is a masterpiece of modern engineering, the factory exhaust note can often feel like it’s wearing a muzzle. If you want your S650 to sound as fast as it looks, you need an upgrade that matches its aggressive DNA.

At DTX Performance, we live for modern muscle. We know that choosing an exhaust isn't just about making noise: it's about finding the specific frequency that resonates with your driving style. Whether you want a deep, old-school rumble or a high-pitched, exotic scream, the right system is out there.

In this guide, we’re breaking down the heavy hitters: American Racing Headers, Borla, Corsa, and more. This is how you unlock the true voice of the S650.

The Foundation of Power: Long Tube Headers

If you are serious about performance, you start at the source. The factory exhaust manifolds on the S650 are restrictive. They are designed for mass production, not maximum velocity. Replacing them with long tube headers is the single most effective way to gain significant horsepower and torque.

American Racing Headers (ARH)

American Racing Headers are the industry standard for a reason. Built right here in the USA from high-quality 304 stainless steel, these headers are designed for one thing: pure, unadulterated power.

When you install American Racing Headers on an S650, you aren't just changing the sound: you're changing the vehicle's physics. Expect a raw, mechanical bark that commands attention.

• Performance Gains: 20-30+ whp with a proper tune.
• Sound Profile: Violent, raw, and high-volume.
• Best For: The enthusiast who wants no compromises on the track or the street.

Kooks Headers & Exhaust

Kooks has been a staple in the Mustang community for decades. Their 1-7/8" stainless headers for the 2015-2026 Mustang GT are engineered for perfect fitment and maximum flow. What sets Kooks apart is the attention to detail in their 3/8" thick laser-cut flanges, which ensure a leak-free seal even under the extreme heat of a supercharged setup.

Check out our Ultimate S650 Mustang Shootout to see how Kooks stacks up against ARH in a head-to-head battle for dominance.

• Performance Gains: Comparable to ARH, with exceptional mid-range torque.
• Sound Profile: Crisp, clean, and authoritative.
• Best For: Precision builds and high-heat applications.

The Voice of the Beast: Cat-Back Systems

If you want to transform the sound of your S650 without diving into the engine bay for a header install, a cat-back system is your best move. This is where you decide the personality of your car.

Borla: The Muscle Legend

Borla offers three distinct sound levels for the S650: Touring, S-Type, and ATAK.

• S-Type: The "Goldilocks" of exhaust systems. It provides a deep, rich muscle car growl that is loud when you want it to be but refined enough for a daily driver.
• ATAK (Addictive Tall And Kilopascals): This is for those who want to be heard three blocks away. It is high-volume, high-aggression, and features a sharp "crack" on every upshift.

Borla’s engineering focuses on eliminating drone, ensuring that your highway cruise remains comfortable while your wide-open throttle pulls remain legendary.

Corsa: No Drone, All Business

Corsa Performance is famous for its Reflective Sound Cancellation (RSC) technology. If you are sensitive to that annoying low-frequency hum inside the cabin during long drives, Corsa is your answer.

• Sport: A sophisticated upgrade over stock that delivers a clear, exotic tone.
• Xtreme: Corsa’s loudest offering. It provides a high-pitched, raspy scream at high RPMs that sounds more like a European supercar than a traditional American V8.

Refinement Meets Power: AWE & Stainless Works

For those who want something outside the "Big Two," brands like AWE and Stainless Works offer incredible value and unique sound signatures.

AWE Touring Edition

AWE has brought their European-inspired precision to the S650 platform. Their Touring Edition exhaust features patented 180 Technology®, which cancels out drone frequencies while maintaining a straight-through design for maximum flow. It’s a sophisticated sound that doesn't sacrifice performance.

Stainless Works Legend Series

The Legend Series by Stainless Works is designed for the purist. It features an X-pipe and quad tips that give the S650 a very specific, hollowed-out muscle tone that is reminiscent of the vintage Trans-Am racers. It’s a high-quality, 304 stainless steel system that looks as good as it sounds.

Understanding the Mid-Pipe: X-Pipe vs. H-Pipe

The mid-pipe is the bridge between your headers and your mufflers, and it plays a massive role in the final sound profile of your Mustang.

1. X-Pipe: Crosses the exhaust gases in an "X" pattern. This creates a higher-pitched, "raspier" sound and generally helps with high-RPM horsepower. It sounds exotic and aggressive.
2. H-Pipe: Connects the two sides with a straight crossover pipe in an "H" pattern. This maintains the classic, deep, "thumpy" muscle car rumble. If you want your S650 to sound like a 1960s fastback, go with an H-pipe.

Build Your Perfect S650 Sound

Selecting the "best" exhaust is a personal journey. Here is our quick decision matrix to help you pull the trigger:

• You want the most power possible: American Racing Headers + High-Flow Mid-Pipe + Tune.
• You want a deep, classic V8 rumble: Borla S-Type Cat-Back with an H-Pipe.
• You want an exotic, high-pitched scream: Corsa Xtreme with an X-Pipe.
• You want zero drone for long road trips: Corsa Sport or AWE Touring Edition.
• You want the loudest car at the meet: American Racing Headers + Borla ATAK.
