Evolution exhaust system for Porsche 911 Turbo (996)

Performance

The high-strength and light-weight titanium we use for building the exhaust system reduces the weight of the rear end of the car by 18,6 kg. This also improves the handling and agility of the car. Because of reducing the backpressure of the engine, the turbo now has a much better throttle response than before and the gas load is also improved. It was also important to us to improve the sound. Our work efforts resulted in a much sonorous and aggressive sound, which gives the turbo a sporty note.

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.
