Frequently asked
Does the Valved Exhaust System fit my Cayenne?
This listing is specific to the Porsche Cayenne (958.2). 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.
How do I know if my Cayenne has PSE?
Check your center console. If there's a button with an exhaust tip icon, your car has Porsche Sport Exhaust (PSE); if not, select the standard exhaust option.
What's different between the PSE and non-PSE versions?
PSE cars use the factory electronic valve actuator. Non-PSE cars get vacuum-operated Helical valves along with Fabspeed's own valve controller and components to run them.
Does installation require cutting?
Yes, minor cutting is required at the factory exhaust break point, with dimple locations on the OEM system used as a reference.
Which option should I choose?
Select Porsche Sport Exhaust (PSE) only if your Cayenne has the factory PSE button on the center console (look for an exhaust tip icon); otherwise choose the standard exhaust option, which includes Fabspeed's own valve controller to operate the valves. Beyond that, the tip finish choice is purely cosmetic.
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.
