Guerrilla Bypass cut-out

The Guerrilla Bypass® personalizes your exhaust


Experience you car mild or wild whenever you want it. Express your feelings or be civilized - Stealth or Guerrilla mode. A Guerrilla Bypass valve in your exhaust makes the sound adjustable.

Guerrilla Bypass is installed into the exhaust tubing before the rear muffler, as a stand-alone cut-out system. With the Bypass closed your car will sound as stock, but once you press the button on the wireless remote control all hell breaks loose. Moreover, bypassing the rear mufflers increases exhaust flow, often resulting in better gas mileage and more power.

The Guerrilla Bypass is the most durable valve system available, thanks to the precision molded stainless steel valve housing with motorized heat resistant valve that always seals air-tight. You can trust this investment in your car to deliver long lasting driving pleasure.
