"No more very loud cold starts due to my high flow cats with long tube headers. I can turn car on in the garage with doors closed and not scare everyone inside the house."

The S550 Mustang GT is an icon of American muscle—but when fitted with aftermarket headers, the sound can become harsh, raspy, and unruly. Valvetronic Designs has created the definitive solution: a valved exhaust system engineered to deliver a smooth, refined, yet aggressive tone worthy of the Coyote V8.
By integrating a center resonator, our system tames unwanted rasp while preserving the deep, muscular character Mustang owners crave. Whether paired with factory manifolds or adapted to aftermarket headers, this is the exhaust that finally gets the S550’s soundtrack just right.
Valves Closed: A composed, neighbor-friendly tone with minimal cabin intrusion—perfect for early mornings or long highway drives.
Valves Open: A commanding, throaty roar with a refined top-end, free of excessive rasp and harshness.
Center Resonator Integration: Smooths exhaust tone and reduces harsh high-frequency rasp.
Vacuum Actuated Valves: Precision control over sound levels and longevity-focused operation.
Weight Reduction: 11.3 lbs lighter than the OEM system for improved handling.
Material: Premium T304 stainless steel for corrosion resistance and durability.
Finish: Dual-wall black tips for a bold, aggressive appearance.
Build Quality: Fully mandrel-bent piping and precision TIG welds for strength and maximum flow.
Reversible Installation: 100% bolt-on design allows you to return to stock at any time.

"No more very loud cold starts due to my high flow cats with long tube headers. I can turn car on in the garage with doors closed and not scare everyone inside the house."
"Love the black tips and the amazing sound. Very excited to have it!!!"
"Excellent Sound, Excellent Service. Shane & Brandon will take care of you"
"Videos genuinely don't do it justice. I'm running catless headers and with the valves closed, it sounds completely stock. With the valves open, it has a deep rumble and it idles like the valves are closed. Great fitment and has a lot of adjustability to dial in the centering."
"Install was great and sounds amazing! I had bought the universal mufflers in the past, but the bolt-on in this kit was super easy to install and works well!"
"Do you make a titanium exhaust for a 2017 Ford Shelby GT350?"
"Love the eshaust was a little hard to get the original clamps from the headers to connect to the h pipe, but once it got on, everything went together and on smoothly. The only thing I miss is how aggressive my downshifts used to be, but I can't complain with how the car sounds now."

"ended up trying this exhaust out after I got the valvetronic set up for my Corvette C8. Very happy with the results. Very easy, simple install, customer service was extremely supportive and attentive when I needed an extra clamp and personally this is the best sounding set up there is. valves closed. I rolled through my neighborhood with no issues whatsoever, but when the valves are open man, this thing sings!!!!"
"Awesome sound, No drone, and quiet when I need it 5/5!"
