FabSpeed Porsche 993 Carrera X-Pipe Catted or Catbypass pipe Conversion Kits



Convert your existing Fabspeed Motorsport HJS Sport Catalytic converter or existing Fabspeed Catbyass X-Pipe into either a Catbypass X-Pipe, or vice versa with a conversion kit. You are basically buying the straight pipes or HJS catted pipes for the revolutionary Maxflo 993 X pipe. These parts are universal for the 993 Bischoff and 993 Gillet X pipes. Beauty of our modular 993 system is that you get catted or no cat in one brilliantly engineered solution.
