Introducing the MRF ENGINEERING E9X BMW M3 Exhaust system. A one of a kind patent pending design, an exotic wail at high RPM's with a 28 rear wheel horsepower gain over stock on 91 fuel.

The most powerful exhaust system on the market to date, with no cabin drone and compliance for the daily driver.

The sound enthusiasts have been longing for out of their S65 powered M3's.
