CTS Turbo is proud to announce the release of our BMW S58 G80/G82 M3/M3 Competition/M4/M4 Competition Crossover Pipe.
One area that can benefit from improvement is the exhaust system’s mid pipe design. The G80/G82 M3 and M4 utilize a Y-style mid pipe, with both downpipes located on the right side of the engine.
The left side downpipe 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.
We have developed a replacement crossover pipe that retains the round shape, eliminating the turbulence and restriction caused by the oval design. By doing so, we expect to increase throttle response and sound.
Features:
- Direct replacement for the factory crossover pipe
- Good match for the aftermarket downpipes
- Durable 304 food-grade stainless steel
- Laser-cut flanges
- Designed using the latest 3D scanning technology
- LHD/RHD fitment
- Lighter than the factory part for some weight savings
