The Akrapovic Evolution aftermarket exhaust system is based on the same layout as the original exhaust system of the GT3 with valve control. A newly developed exhaust manifold with 100 cpsi sports catalysts guarantees an increase in power and torque, as do the newly developed and optimized pre mufflers. But the real plus of this exhaust system is the weight reduction of 17 kg, while it maintains the original layout and functionality of the exhaust caps.
