Supersprint BMW E46 M3 Stainless Center H-Pipe - Non-Resonated Dual 2.5"

Enhance the performance and sound character of your BMW M3 (E46) 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.
