Description
The Evolution Racewerks Competition Series Mid Pipes are engineered for the 2021+ BMW M3 (G80) and M4 (G82) equipped with the S58 twin-turbo engine. By removing the restrictive factory resonators, these mid pipes increase horsepower, torque, throttle response, and turbo spool while producing a more aggressive exhaust tone without unwanted drone when used with the factory downpipes and rear muffler.
Constructed from 100% 304 stainless steel with mandrel-bent 3" (80mm) piping, these mid pipes maintain smooth exhaust flow and reduce backpressure. An H-style crossover equalizes pressure between left and right banks, improving low-end torque and reducing drone compared to X-style crossovers. The H-pipe design aligns with BMW’s own engineering philosophy to maintain ideal flow characteristics.
Billet CNC-machined stainless steel flanges, retained factory bracket hangers, and laser-cut TIG-welded brackets ensure a precise fit and durable assembly. High-quality clamps are included for secure attachment to the rear exhaust section. These mid pipes are compatible with both factory and aftermarket exhaust systems designed for OEM mid pipe connections.
