ESS Tuning - Stainless Steel Exhaust (Axle Back) - BMW E9X M3

The ESS E9X M3 axle back is a great addition to the M3. Improving the sound and performance of the M3 while retaining a very refined sound was our top priority when developing this system. Our exhaust is designed to bolt directly up to the OEM mid section and most aftermarket. Power increase of up to 8 HP over stock and 8 lbs less in weight than the factory exhaust. For maximum power increase we suggest pairing our axle back exhaust with our performance X-pipe and specially designed NA performance software. Features: - Made in the USA - 75mm Quad Tips - Full Stainless Steel Construction - Includes Connecting Pips - Satin Silver or Ceramic Black Finish Models Supported 2008-2013 BMW E9X M3
