Evolution Racewerks Sports Series Resonated Mid Pipes – BMW M3 / M4 (G80 / G82, S58)

OVERVIEW

Evolution Racewerks' Sports Series Resonated Mid Pipes for the twin-turbo S58 engine fit the 2021 and newer BMW M3 (G80) and M4 (G82). They swap the restrictive factory resonators for free-flowing units, which raises the maximum horsepower curve, brings the torque curve on sooner and holds it higher and longer, and improves throttle response and turbo spool.

The resonated version is designed to sound close to factory rather than louder. It suits owners who do not want more volume than stock, or who already run aftermarket downpipes or an exhaust that has become too loud, while still gaining performance. Mandrel bent 3" (80mm) tubing runs through the full mid section.

An "H" style crossover equalizes pressure between the left and right exhaust pipes, which promotes flow and reduces droning. ER tested "X" and "H" designs and found the "H" crossover reduced droning and improved low end torque; BMW uses an "H" crossover on the factory mid pipe as well. The pipes are built from 100% 304 grade stainless steel, 100% TIG welded in house in the USA, with CNC precision cut billet stainless flanges. The factory bracket hanger is retained, and high quality exhaust clamps join the mid pipes to the rear muffler section. A 3-piece design lets the set ship by standard ground and air carriers instead of truck freight.
