About RPI Exhaust Systems

RPI exhaust systems are designed in house and offer an excellent balance of performance and sound. All RPi exhaust systems are tested under strict conditions to ensure the most performance for your car. For those who want better sound and performance without drawing a lot of attention, we have the ST series. The GT and GtRace series exhaust systems are designed for maximum sound and power. All RPi exhaust systems are made in the USA using top quality T304 stainless steel and come with a Limited Life Time Warranty.


Aggressive Sound & Exceptional Performance

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 GTM Race system for the M3.
