Enhance the performance and sound character of your BMW E46 M3 with the Supersprint Stainless Center H-Pipe (Non-Resonated). Designed specifically for the S54-powered E46 M3, this mid-section replaces the factory center section with a high-flow stainless steel twin-pipe layout that improves exhaust efficiency and sharpens the exhaust note.
Supersprint engineers this component using dual 63.5 mm piping with an H-pipe crossover to balance exhaust pulses between both banks of the S54. The non-resonated configuration eliminates the factory resonator, allowing the engine’s natural tone to come through more clearly and providing a more aggressive sound profile.
This center section bolts directly to the OEM catalytic converters and integrates with factory or Supersprint rear mufflers, making it a versatile upgrade whether you are maintaining a largely stock system or building a complete Supersprint exhaust setup.
