S / GTS Secondary Competition Link Pipes
Secondary catalytic converter bypass pipes for the Porsche Cayenne 958 S and GTS (2011+), replacing the restrictive factory cats with much less restrictive straight-through pipes made from polished T304L stainless steel. Fabspeed's dyno testing showed an 11 whp gain with sharper throttle response, plus an aggressive exhaust note for a more exotic sound. Direct bolt-on replacement for the heavy factory cats. Because it removes the factory catalytic converters, it's not CARB or EPA certified, so it's intended for closed track and off-road use only, not public roads.
Frequently asked
Does the S / GTS Secondary Competition Link Pipes fit my Cayenne?
This listing is specific to the Porsche Cayenne (958.1). Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
Is this legal for street driving?
No, it removes the factory cats so it's not CARB or EPA certified — closed track and off-road use only.
How much power does it add?
Fabspeed's testing showed an 11 whp gain along with sharper throttle response.
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?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
