E46 M3 Section 1 Rogue Engineering Rasp Pipe
Eliminate exhaust rasp with this easy-to-install performance replacement pipe
The Rogue Engineering E46 M3 Rasp Pipe is the ideal way to get rid of your M3’s factory exhaust rasp, so you can truly enjoy the sound of your S54 without the metallic chainsaw noise of the factory exhaust at high RPM.
During the development process, Rogue Engineering was able to tune out the factory rasp without the added expense of needing to replace another section of of the exhaust system. This section alone will successfully get rid of the rasp even with the factory muffler section, and because it’s a direct bolt-in replacement, it’s a quick and easy installation with a price that won’t break the bank.
While there are a few other choices on the market, the Rogue Engineering Rasp Pipe is one of the few that can truly say that performance is uninhibited by its installation. The cheaper "muffler style" designs use a one-piece unit in an attempt to match the RE results while cutting costs, but those have negative effects.
With its direct bolt-in factory fit, the RE Rasp Pipe does its job while you run virtually any exhaust you wish, whether stock or aftermarket.
