Billy Boat 993 Muffler By-Pass Pipes (1995-1998)

These pipes work to bypass the Muffler itself, for a non-restricted exhaust note from your Porsche 993. By doing this, two of the Cats are eliminated as well, and the Porsche 993 is really allowed to let loose its most natural and aggressive exhaust noise. Designed and manufactured by Billy Boat Performance Exhausts from the highest quality aircraft grade stainless steel, this is a fantastic upgrade for any Porsche 933 owner who wants an extremely agressive exhaust noise and does not mind the added cabin drone.
