Slip-On exhaust system for BMW M3 (E90, E92, E93)

The power increase is about 3 HP. The torque is nearly constant at 4 Nm/3 lbs-ft over the stock. That is the real joy of driving: high speed engine benefits in daily practice due to the torque increase. It improves the agility in the lower rpm-range. Also, the engine is stronger in the higher rpm-range and the elasticity is improved. The improvement of acoustics played an important role in the development. The Akrapovič exhaust system amplifies and rectifies the beautiful sound of the 8-cylinder motor, without appearing invasive or having disadvantages in the daily use. All M3 systems are available with either titanium or carbon fiber tail pipes.
