BMW RPI Exhaust - 3 Series E92 M3 GTM (Axleback/Catback)

RPi's GT and GTM Race exhaust systems are the pinnacle of power. Providing a monstrous 35ft/lbs and 28whp over the factory 400+hp, the GTM Race systems offers quite the "bang for the buck." The system is made of T-304 stainless steel and comes with a limited lifetime warranty. All RPi exhaust systems are 100% made in the United States and are tested under extreme conditions*. This makes the GTM Race exhaust far superior to imported systems that are far from proven.

*Race Precision dyno tests all their products in doors with the hood closed. All tests are done with no cool down period and numbers are only provided if the power numbers can be backed up consecutively. Many manufacturers compare a heat soaked baseline run with a cool after run which is not accurate. Although the numbers are great for marketing, the products fail when compared to RPi products.
