Shark Werks Muffler Bypass System
for 997GT3 & 991GT3 in Exhaust
The Shark Werks GT3/GT3Rennsport Muffler Bypass System which has been designed, developed and tested on the Shark Werks 2007 997GT3Rennsport (ZKERMIT), dramatically improves the sound of any 997 GT3 or GT3RS, including the 2010+ MkII models. There is no noticeable additional cabin drone or resonance. With the Sport Chrono and factory exhaust valves still in place you can drive with our system turned "on" for a more aggressive sound or off for daily driving with the flick of the factory sport button. Uncorking the car and listening to her head down the front straight of your favorite track at 8400rpms is something we highly recommend you do.
