Fabspeed Porsche 981 Cayman GT4 Competition Conversion Kit - For Fabspeed Valvetronic Exhaust



Forgo valves and drop 11lbs as you convert our Valvetronic Exhaust into a valveless Competition Exhaust for the lightest and most aggressive system.                                                          

Unleash the full roar of the 3.8L GT4 with our Competition Conversion Kit. We've had numerous owners of our Valvetronic Exhaust system ask for a valve delete to shed weight - for those who like it loud the valves are not necessary. The CCK easily bolts in place using existing hardware and is reversible at any time.
