We at Sonic MS are proud to present RPi's brand new LIMITED EDITION GTC exhaust mufflers for the E92 / E93 M3.

This limited edition GTC exhaust features a hand crafted muffler with laser cut end caps. The GTC offers the same performance as our popular GT and GTM systems but is 20-30% quieter. Less drone, quieter cold start and lower overall sound makes the GTC a great exhaust for the daily driven weekend racer. All RPi exhaust come with a limited lifetime warranty.

It's proudly crafted in the United States out of high quality T-304 stainless steel, and weighs approximately 37 lbs, saving 22 lbs from the bulky OEM equipment. Comes with connecting pipes for a 100% bolt on installation.

RPi GT X-Pipes / V2 Cat Delete Pipes - E9X M3

We also carry RPi's X-Pipes and V2 Cat Delete Pipes, the perfect complement to the GTC rear section and completes the full "race" exhaust system.

This system has dyno proven gains of 28whp and 35 ft/lbs of torque when coupled with the GTC Rear Section. Unlike some tuners, RPi employs rather strenuous dyno testing standards.

All tests are done with no cool down period and numbers are only provided if the power numbers can be backed up consecutively with consistent results.
