Description
The Evolution Racewerks Competition Series Mid Pipes are engineered to increase performance and enhance exhaust flow on your 2020+ BMW X3M or X4M equipped with the S58 twin-turbo engine. By removing the restrictive factory resonators, these mid pipes deliver a significant improvement in horsepower, torque, throttle response, and turbo spool. The result is a more aggressive exhaust tone without introducing unwanted drone when paired with factory downpipes and the OEM rear muffler.
Designed with mandrel-bent 2.75" (70mm) stainless steel piping, the mid pipes maintain smooth, uninterrupted exhaust flow. An H-style crossover is incorporated to balance exhaust pressure between both banks, improving low-end torque and reducing drone. Testing revealed that the H-pipe provided superior drivability and noise characteristics compared to an X-pipe, aligning with BMW’s own design philosophy.
Constructed from 100% 304 stainless steel and precision TIG welded in-house in the USA, these mid pipes deliver exceptional strength and durability. CNC-machined billet flanges ensure a perfect fit, while stainless steel hangers retain factory mounting points. High-quality exhaust clamps are included for secure installation. These mid pipes are fully compatible with both factory exhaust systems and aftermarket systems designed to mate with factory mid pipes.
