Slip-On exhaust system for Porsche 911 GT3/RS (997)

SLIP ON System
PORSCHE 911 GT3/RS type 997
(3.8L - mandatory carbon exhaust diffuser required)
Titanium Muffler with fitting material, fits on original configuration, TP double round dia 100 mm SPORT MODE ACTIVE


The AkrapoviÌ_å_ 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 AkrapoviÌ_å_ 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 AkrapoviÌ_å_ 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 AkrapoviÌ_å_ 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 AkrapoviÌ_å_ 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.
