We begin with our very lightweight center muffler made of our proprietary titanium alloy. Replacing the stock center muffler alone reduces the weight at the back of the car. Each center muffler kit also includes beautifully handcrafted carbon fibre bumper inserts with integrated titanium exhaust tailpipes. Through careful design we were able to produce an exhaust system that has a deep and aggressive sound without being unpleasant or intrusive during normal driving conditions. The next option is to replace the stock link pipes with the optional available Akrapovič variant made from titanium and incorporating high-flow catalytic convertors. In order to increase the power beyond the limit of 500 hp, ECU reprogramming will be required.

When installing Akrapovič aftermarket optional down pipes with sports catalytic converters or without catalytic converters, which are developed for use on closed tracks only, remapping the ECU is mandatory. When installing Akrapovič aftermarket exhaust system that was developed for use on closed tracks, we recommend remapping the ECU in order to prevent potential »check engine light« warning signals.

Akrapovič’s Slip-On Line represents the first step in the exhaust system tuning process and the muffler can easily be installed onto the Porsche GT3’s original system. Built from hi-grade titanium and finished with two eye-catching double round tailpipes, this entry system makes the GT3 more powerful and lighter, and gives the car that unique Akrapovič sound, while still meeting ECE specifications. Designed to make the car stand out from the crowd and increase its appeal even more, the visual delight of the Akrapovič Slip-On can be further enhanced with the addition of an optional carbon- fibre rear diffuser. Beautifully handcrafted from the finest materials and designed to enrich the exclusive look of the titanium exhaust system, the diffuser is a must-have extra for any discerning owner.
