The Akrapovič aftermarket Slip-On system is based on the same layout as the original exhaust system of the GT3 with valve control. In comparison to the aftermarket Akrapovič Evolution exhaust system, the Slip-On does not contain an exhaust manifold with a 100 cpsi sports catalyst, but rather only a titanium muffler with two double round tail pipes. The muffler is easily installed on the original exhaust system. Another advantage is that it is homologated for road use.
A Porsche 911 GT3/RS (997) that is equipped with an Akrapovič Slip-On exhaust system is more powerful and lighter, even though the exhaust system is not replaced in its entirety. The sound of its six valve engine is also noticeably improved. A look at the numbers reveals that the Slip-On offers a 2 kg weight reduction in the rear of the Porsche 911 GT3/RS of and a 4 HP and 3 Nm increase in power. The reduced weight provides better steerability and the increased power additionally spices up sports driving, because the changes offer better lap times. Two tail pipes, measuring a 100 millimeters in diameter, make it clear that the Akrapovič Slip-On system is no ordinary exhaust.
Slip-On system, homologated:
* titanium end muffler
* titanium tail pipes*
Hard facts:
* plus 4 HP (at 7.390 rpm)
* plus 3 Nm (at 6.040 rpm)
* minus 2 kg
* fits on original configuration
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.
