See Emissions Details
Dinan's unique muffler design effectively reduces back-pressure for improved flow, resulting in measurable power gains. Manufactured from 304 stainless steel inside and out for superior resistance to corrosion as well as a significant reduction of weight. And from those aggressive-looking ceramic-coated tips flows an exhaust note that will be music to the driving enthusiast's ears.

The Dinan exhaust delivers exactly what the M3 owner demands in a performance muffler; increased power, reduced weight, a look that means business and the throaty exhaust note you'd expect from an M3.

Features:

  • More Power: + 7 HP @ 8000 RPM + 5 LB-FT @ 5000 RPM (w/ software)
  • Drone abatement technologies used to reduce cabin resonance
  • Enjoyably louder, sportier sound
  • Quad 3" black ceramic coated and laser engraved exhaust tips
  • 15 lbs. lighter than stock (43 lbs. vs. 58 lbs.)
  • 100% 304 stainless steel construction
  • Uses the factory brackets and hangers for a factory-like fitment
