More Sound. More Power. No Drone.

Are you looking for more sound out of your 997/991 GT3 without sacrificing street drivability? Look no further than the TPC Racing Active Side Muffler Bypass pipe. It provides cup car sound and performance when you want it, while eliminating unwanted cabin drone and excessive noise in normal street conditions. All this while improving performance and handling.

How it works

Using a factory-style actuator-controlled valve, the TPC Racing Active Side Muffler Bypass System provides cup car sound and performance in higher rpm/higher load ranges, while eliminating unwanted cabin drone and excessive noise. Its lightweight design saves 40 lbs from the OEM side mufflers, resulting in improved handling. Better exhaust flow management allows for increased torque between 2,600 and 5,600 rpm, as well as increased horsepower between 5-8,250 rpm.
