Don't be fooled by other exhausts systems and phony dyno sheets. All RPi exhausts are RPi* tested and come with a limited life time warranty. Our popular GT series exhaust offers an aggressive sound and exceptional performance at a great price. This exhaust is 100% bolt on with no other parts/hardware to purchase. Expect a 5-10whp gain with the rear muffler section. For an even more aggressive sound and huge hp/tq gains, ask about our GT Race system for the M3.

*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.
