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.

The left side downpipe on the S58 connects to a "crossover" pipe that runs beneath the transmission and links up with the mid pipes on the left side. Unfortunately, the stock shape of the crossover pipe is oval to create enough clearance underneath the transmission. This alteration from a round tube to an oval causes turbulence within the pipe, leading to a restriction in exhaust flow. CTS Turbo has designed a crossover pipe to eliminate this turbulence that is created by the factory system and ditched the oval design for a round circular design for increased flow and horsepower!
