Akrapovič developed the Evolution aftermarket exhaust system for the 997 Turbo, which is made of titanium. The turbines of the turbochargers on these cars strongly absorb the sound of the engine; Akrapovič was able to change that. They were able to give the otherwise quiet 997 Turbo an aggressive sound without disadvantages during daily use.
Two turbochargers and two air intercoolers considerably increase the weight of the Porsche 997 Turbo engine in comparison to the naturally aspirated model. The lighter exhaust system frees up some weight in the rear end and centralizes the weight in a more balanced manner. The limit range of the vehicle adjusts upwards and so a higher transverse acceleration is possible.
Akrapovič achieved an increase in power, torque, and reduction of weight by 11 kg, because of a new 100 cpsi hi-flow metal catalysts and the capacity-optimized layout of the muffler.
