Fabspeed Porsche 911 Turbo 930 RENNKRAFT Sport Cat and Comp. Link Bypass Pipe (1976-1989)


Replaces the restrictive ancient factory catalytic converter with either a HJS 200-Cell Catalytic Converter or a straight-through pipe to maximize power and sound. The patented REKRAFT design allows you to easily swap between running a catalytic converter to stop smells and keep the environment clean or install the cat bypass pipe for racing use. It retains stock OEM Porsche rear 911 Turbo 930 mufflers so the car looks original but sound and performs great.
