Description
Enhance the performance and sound of your BMW M3 or M4 with the MAD Resonated H-Pipe Midpipe, engineered specifically for the S58-powered G80, G81, G82, and G83 chassis. This upgraded midpipe replaces the restrictive OEM design, offering improved exhaust flow and a more aggressive, refined tone without excessive drone.
The MAD H-Pipe retains the factory-style dual pipe layout with an integrated crossover section, helping to maintain backpressure balance while elevating the acoustic character of the exhaust. In place of the OEM secondary catalytic converters and oversized resonators, the MAD system incorporates compact, finely tuned resonators that increase volume and clarity while managing unwanted frequencies.
Perfect for enthusiasts seeking a sportier tone with a refined finish, the MAD Resonated H-Pipe is compatible with both factory and aftermarket downpipes and axle-back systems. No cutting is required when paired with MAD or other compatible aftermarket axle-backs, making installation seamless.
