Muffler Bypass Exhaust System

Muffler bypass exhaust system for the Porsche 997 Turbo (2006-2009), a very aggressive straight-pipe replacement for the factory system available in Street or Race configuration. The Street option keeps 200-cell HJS sport cats in place with no catalyst-related check engine light, while Race swaps in cat bypass pipes for maximum flow off-road. Built from 14-16 gauge CNC mandrel-bent T304L stainless steel, it bolts directly onto the factory system, saves 20 kg from the rear of the car, and includes Deluxe Quad-Style Tips in your choice of polished stainless or satin black.

What's the difference between Street and Race?

Which option should I choose?
Choose STREET if you want 200-cell HJS sport catalytic converters retained, with no catalyst-related check engine light. Choose RACE for cat bypass pipes instead, which flow more freely but are intended for off-road use only.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
