The factory midpipe mutes much of the engine's personality, leaving the exhaust sounding subdued. The MAD Resonated H-Pipe restores the deep V8 tone by allowing both exhaust banks to communicate through a precision-engineered H-pipe while incorporating high-flow resonators to smooth out unwanted frequencies. The result is a deeper, fuller exhaust note with improved character, reduced harshness, and virtually no drone.

Unlike a single midpipe, the resonated H-pipe retains the factory dual-exhaust layout and enhances the natural cross-plane V8 rumble. The integrated resonators help eliminate unwanted resonance while preserving a strong, aggressive sound under acceleration. It's the perfect balance for owners looking for a premium exhaust tone that's sporty when you want it and civilized when cruising.

Whether paired with the factory axle-back or the MAD axle-back, the MAD Resonated H-Pipe transforms the sound of the G90/G99 M5 without sacrificing refinement.
