ESS Tuning

The Akrapovic Evolution Exhaust System for BMW M3 consists of flow optimized link pipes with 2 x 100 cpsi sports catalysts and integrated resonators as well as a completely newly developed and now split-end mufflers. This exhaust system, made fully from titanium, reduces the overall weight when compared to the stock system by about 23 kg.

From approximately 2500 rpm on, the power increase is about 24 HP. The torque is nearly constant at 35 Nm 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 noticeably. Also, the engine is stronger in the higher rpm-range and the elasticity is improved considerably.

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.

Especially developed ESS ECU software is available for this exhaust system as well, to optimize torque and power as well as to avoid any emissions related check engine lights/codes.
