Porsche 964 Carrera European Pre-Muffler Cat Bypass Pipe (1989-1994)

Excluding GST
Replace your ancient 964 factory catalytic converter with a straight-thru resonated pipe resulting in more horsepower, improved throttle response and throaty gutsy sports car sound.
The straight through design of this cat-bypass pipe means you'll get a much louder throatier sound from your 964. However, because it is resonated it you won't experience any rasp or harsh tones.
