Rasp Terminator for the E46 M3 (also for MZ3 and Z4M) is a tuned front section that: Greatly reduce rasp from the S54 engine Balance exhaust pressure for each bank with H-pipe crossover The S54 rasp is excessive and tuning it out requires the right combination of resonators, placement, and tubing size. CPI designed their own section 1 after other designs on the market fell short. Rasp is reduced by approximately 80% on a M3 equipped with aftermarket headers. The latest RTX incorporates an H-pipe crossover that equalizes exhaust pressures in both banks before they merge for section 2. This reduces turbulence and improves exhaust flow. While not designed to gain power and torque, dyno testing showed slight gains with this system. Fitment has also been improved for better ground clearance. Tubing is a full 2.36" (60mm) and 304 stainless steel throughout. It will bolt on to most headers and to any section 2 that uses the factory-style flanges.

Your engine's air fuel ratio needs to be dead on. Worn out factory pre-cat oxygen sensors delay vital data to the DME, leading to sub optimal fueling, lost horsepower, and dangerous hesitation under load.
