Frequently asked
Does the Valved Cat-Back Exhaust System fit my Cayenne?
This listing is specific to the Porsche Cayenne (E3). 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.
Does this fit the Cayenne Coupe GTS or Turbo GT?
Not if those models are equipped with factory Porsche Sport Exhaust (PSE); Fabspeed states this system will not fit 2021+ Coupe GTS or Turbo GT with PSE.
Can I reuse my factory exhaust tips?
Only if your car has four muffler outlets; the reuse-OEM option won't work on factory setups with two outlets.
Does installation require cutting?
Yes, minor cutting is required; see Fabspeed's instructions for the correct cut point on the OEM system.
Which option should I choose?
Reusing your OEM tips only works if your Cayenne's factory exhaust has four muffler outlets, not the two-outlet setup. If you're unsure, or want a fresh finish, the polished, satin black, carbon fiber, and titanium tip options are all available at the same extra cost over reusing OEM.
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.
