BMW E46 M3 Performance Exhaust Systems

BMW E46 M3 Performance Exhaust Systems BMW Performance exhaust systems are tuned by in-house BMW engineers to subtly enhance the sound and performance of your BMW. They have engineered these systems to fit perfectly, sound beautiful, utilize advanced materials, and blend with the styling of your car. BMW Performance exhausts are not too loud - focusing on enhancing the sound rather than blaring it. By opening up the exhaust and removing restrictions, the engine can work less to move the exhaust gasses through the system. This means a bit more power in addition to that sexy growl they produce.

GruppeM 60mm Titanium Exhaust System  --  BMW E46 M3

GruppeM designs some of the highest quality intakes and exhaust on the market. Using advanced techniques to get optimized efficiency using specific pipe diameters, they are able to produce an exhaust that not only performs amazingly, but sounds amazing too. Gruppe M's exhaust systems are designed to fit the same as the stock exhaust, eliminating guess-work, allowing for quick and clean fitting systems that require no custom fabrication or assembly.

  • Ultra-lightweight titanium construction 
  • Racy, high-pitched exhaust note at high revs and heat color gradation
  • Dual 70mm exhaust tips
  • Shot processed stainless steel tail end (made of stainless steel)
