Evolution exhaust system Porsche 911 GT2 / GT2 RS (997)

Performance

Because of comfort, durability and strict noise requirements regarding the exhaust system, some kind of compromise had to be made. This was reason enough for us to develop a real aftermarket “sport-exhaust version” for this super sports car. Our requirements were very simple: lighter, more powerful and better sounding exhaust system. Two hiflow 100 cpsi metallic cats, larger tube diameters, measuring not 55, but 60 mm, reduced the power-consuming backpressure by more than 50 %. This resulted in a power increase of 41 HP, a torque increase of 74 Nm and weight savings of 5 kg, compared to the stock system.

Evolution system:

• titanium header set
• titanium link pipes with integrated 100 cpsi catalysts
• titanium central muffler
• titanium tail pipes

Hard facts (100 cpsi cat version):

• plus 41 HP (at 4.080 rpm)* 
• plus 74 Nm (at 4.020 rpm)* 
• minus 5 kg*

* GT2

When installing an aftermarket Akrapovič Evolution exhaust system, which is developed for use on closed track, we recommend remapping of the ECU to prevent possible “engine check light” warning signal.
