Akrapovič’s Slip-On Race Line represents the first step in the exhaust system tuning process and it 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, sporty Akrapovič sound.The mandatory tail pipe set TP-T/S/19 needs to be ordered separately.The Slip-On Race system can be optionally combined with Link Pipe Set (Titanium) that retains stock headers and removes stock side mufflers, or it can be upgraded into a full Akrapovič exhaust system, either with combining it with Evolution Race Header Set without valves or Evolution Header Set with side mufflers and valves.THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
