The 2024+ S650 Mustang is the pinnacle of the internal combustion pony car. With the Gen 4 Coyote V8 pumping out up to 500 horsepower in Dark Horse trim, the platform is a masterpiece of modern engineering. But there is a problem. From the factory, even with the active valve exhaust, the S650 sounds restrained. It’s muffled by regulations and massive resonators that choke the life out of that 5.0L scream.

At DTX Performance, we believe your Mustang should sound as fast as it looks. You didn’t buy a muscle car to blend in; you bought it to be heard. Today, we are breaking down the three heavy hitters in the S650 exhaust world: Borla, Corsa Performance, and American Racing Headers (ARH).

This isn't just about volume. It’s about tone, drone, and the raw performance gains that come from high-flow engineering. Let’s get into the dirt.

Push the Limits: The Borla Heritage

Borla is a name synonymous with American muscle. For the S650, Borla didn't just recycle old designs; they utilized their Polyphonic Harmonizer technology to tune the Coyote’s note into something truly special.

Sound Quality: The Deep Growl

Borla offers two primary flavors: the S-Type and the ATAK.

• S-Type: This is the "Goldilocks" exhaust. It provides a deep, throaty rumble at idle and a clear, muscular bark under wide-open throttle. It sounds like a Mustang should: classic, powerful, and authoritative.
• ATAK: If you want to be the loudest person at the local meet, this is your weapon. The ATAK (Abusive Tongue and Cheek) is aggressive. It’s high-volume, high-frequency, and designed to crackle on the downshifts.

Drone Control: Zero Tolerance

Borla is famous for its "No Drone" guarantee. They use specific muffler lengths and internal geometry to cancel out the frequencies that cause that annoying cabin hum at highway speeds. You can cruise at 70 MPH with an ATAK system and still hold a conversation: until you drop a gear and disappear.

Performance Gains

Expect a solid bump in flow. By replacing the restrictive factory mid-section and mufflers, Borla systems typically net a gain of 10–15 horsepower and a similar increase in torque. It’s about more than the numbers; it’s about the throttle response.

Build for Precision: The Corsa Scream

Corsa Performance takes a different approach. While Borla leans into the traditional deep muscle sound, Corsa aims for an "exotic" high-pitched scream.

Sound Quality: The High-Frequency Master

Corsa systems, particularly the Xtreme series for the S650, are known for their "hollow" and raspy tone. It makes the Coyote sound less like an old-school truck and more like a high-revving European supercar. At high RPMs, the Corsa system is piercing. It cuts through the air with a distinct, sharp note that is instantly recognizable.

Drone Control: RSC Technology

Corsa’s claim to fame is Reflective Sound Cancellation (RSC). They don’t use packing material that breaks down over time. Instead, they use airwaves to fight airwaves. This technology is incredibly effective at eliminating drone while maintaining maximum volume outside the car. If you are sensitive to interior resonance, Corsa is often the top choice.

Performance Gains

Like Borla, Corsa focuses on a straight-through design. The S650 Corsa systems eliminate the heavy factory resonator, replacing it with a high-flow X-pipe. This reduces backpressure and lets the Gen 4 Coyote breathe, resulting in measurable gains across the entire power band.

Select Raw Power: American Racing Headers (ARH)

If you want to move beyond a simple cat-back and unlock the true potential of the S650, you look at American Racing Headers. ARH doesn't just change the sound; they change the engine’s soul.

Sound Quality: Unfiltered Aggression

When you install a set of ARH Long Tube Headers combined with their full 3-inch exhaust system, the sound is violent. It is raw, mechanical, and loud. Because you are replacing the factory manifolds and high-density catalytic converters with tuned long tubes, the exhaust pulses are more distinct. The idle is choppier, and the top-end scream is deafening.

Drone: The Trade-Off

With long tubes, you are going to get more noise in the cabin. That is the reality of performance. However, ARH tunes their systems to be as livable as possible. While there is more "engine noise" present, the specific exhaust drone is well-managed through high-quality resonators.

Performance Gains: The Heavyweight Champ

This is where ARH wins. A cat-back exhaust is for sound and some flow; headers are for power. Installing ARH long tubes on an S650 Mustang can net gains of 25–40+ horsepower, especially when paired with a custom tune and a high-performance cold air intake. If you are building a drag strip monster or a track-day hero, ARH is the foundation of your build.

Shop the Comparison: Which One Wins?

Selecting the right exhaust for your S650 depends on your ultimate goal. We’ve broken it down by the "Mustang Lifestyle":

1. The Daily Driver (Comfort & Class): Choose the Borla S-Type. It gives you the muscle car identity without annoying your neighbors every single morning. It’s professional, deep, and perfectly balanced.
2. The Weekend Warrior (The Exotic Scream): Choose the Corsa Xtreme. The high-pitched note is addictive. It makes every tunnel run an event and ensures you stand out from the sea of other Mustangs at the show.
3. The Pure Enthusiast (Maximum Power): Choose American Racing Headers. If you are chasing a 10-second quarter-mile or just want the most aggressive setup on the street, headers are mandatory.

If you are looking for an alternative that offers a unique tone and premium construction, you should also check out the AWE Touring Edition Catback for the S650. AWE has made a massive splash in the modern muscle scene with their 180 Technology, which provides a sophisticated sound without any drone.
