Boost activated exhaust diversion valve - have the best of both worlds!
Full power of an open exhaust at full throttle and high boost, but quiet for cruising. The ultimate screamer pipe.
No wiring, just a simple and reliable boost referance line is all that is required to open the exhaust valve when boost rises above roughly 0.5 Bar (~7 psi).
You could always plumb in a manual enable valve to inhibit operation for full stealth mode. Could also be mapped with an ECU output and solenoid valve.
No more climbing underneath the car to modify the exhaust for track days.
Stainless Steel. 3" & 3.5" sizes available.
