BMW Exhaust System Upgrades for BMW E46 (1999-2005) M3

Clear BMW chassis
A performance exhaust is a modification that you get constant benefit from - at every change of the throttle you are rewarded with that tuned sound. It's not like other modifications where you may not realize all of its benefits all the time. It's an upgrade that you enjoy at all times when you're behind the wheel. We offer exhaust upgrades from multiple performance manufacturers like Borla, Corsa, Supersprint, and Akrapovic but we have also developed or sourced other exhaust systems to meet specific needs.

The Active Autowerke Exhaust SECTION 1 only comes into play if the E46 M3 already has a performance header already installed. One will experience a high smell of unburnt fuel. (due to the open exhaust w/o any catalysts) and development of a RASPY like sound of which the BMW S54 engine is notorious for with the BMW Stock Section 1 when equipped. This raspy like sound is a matter of engine sound harmonics at a specific RPM range, a sort of resonance that is very loud and noticeable when the engine is revving at or above 4,000 rpm

With the Active Autowerke Exhaust SECTION 1 installed, the BMW performance gains are about the same as running the factory section 1. However, that's impressive considering the exhaust flow is also being filtered while running through a pair of 100 cell catalysts. The power and performance is still there.

E46 Section One Features:

  • Dyno-tested & Track Proven
  • Brushed 100% 304 stainless steel construction
  • Pair of 100 CELL Hi-Flow metallic exhaust catalysts included
  • Easy installation, no instructions necessary
  • Two-year warranty with free tech support
