In addition to providing Porsche AG with a titanium exhaust system for the GT2, we also developed the aftermarket Evolution complete exhaust system for the Turbo, which is made of titanium. We achieved an increase in power, torque and reduction of weight by 14 kg, because of the complete new manifold system, new 400 or 100 cpsi (customer’s choice) hi-flow metal catalysts and the capacity-optimized layout of the mufflers. *All other Akrapovic products are available through WORKS
- Evolution system (400 cpsi homologated):
- * titanium header set
- * titanium link pipes with integrated 400 or 100 cpsi catalysts
- * titanium end muffler
- * titanium tail pipes
- Hard facts (100 cpsi cat version):
- * plus 30,6 HP (at 5.970 rpm)
- * plus 38,3 Nm (at 3.990 rpm)
- * minus 14,11 kg
- Hard facts (400 cpsi cat version):
- * plus 24,1 HP (at 6.030 rpm)
- * plus 36,6 Nm (at 3.740 rpm)
- * minus 14,11 kg
- When installing an aftermarket Akrapovic 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.

Features
- Two turbo chargers, two air intercoolers considerably increase the weight of the Porsche 997 Turbo engine in comparison to the atmospheric model. The lighter exhaust system unburdens 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. The combination of improved power to weight ratio (through an increased efficiency of 30,6 HP), torque progression by 38,3 Nm, and the positive effects in connection with driving dynamics enhance the performance of the Turbo distinctively. Furthermore, we thought it important to improve the sound. The turbines of the Turbo strongly absorb the sound of the engine, but we were able could compensate for it. We were able to add the otherwise quiet Turbo a sonorous and aggressive sound impression without disadvantages in the daily use.
