Overview
Engineered for one car.
FitsFord Mustang 2.3 EcoBoost (S550) · 2.3 L EcoBoost turbo I4
Valvetronic cat-back system for the Ford Mustang 2.3 EcoBoost. The single outlet of the turbo feeds a Y-pipe that splits into twin over-axle pipes; electronically controlled valves sit in front of the two rear mufflers, each finished with a large polished tailpipe.
Switch between a discreet tone for everyday driving and the full sound when you want it.
Stainless steel
Durable, corrosion-resistant and finished to a clean, even polish.
Bolt-on fit
Made for the original mounting points — no cutting, and the factory system can go back on.
Fitted by a dealer
Authorised dealers install, leak-check and set up the system on your car.
Sound
One switch, two characters.
Comfort: the valves stay shut and the gas takes the long way through the silencer — calm on the motorway, quiet on a cold start.
Sport: the valves open and the gas takes the straight path — sharper response and the full voice of the engine.
Visualisation, not a recording. Your dealer sets the valves up for your car.

Questions about this system
Will it fit my exact car?
Each system is made for specific models and engines. Send us your car and we confirm the fit before anything is ordered.
Can the car go back to stock?
Yes. The system bolts on to the original mounting points, so the factory exhaust can be refitted — keep it for resale or lease return.
Who installs it?
Authorised USUS dealers. They fit the system, check it for leaks and set up the valves in every mode.
