Frequently asked
Does the C8 Z06 Sport Cats fit my Corvette Z06?
This listing is specific to the Chevrolet Corvette Z06 (C8). 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.
Do I need an ECU tune to avoid a check engine light?
No. These cats are designed to flow enough for real gains while still scrubbing the exhaust sufficiently to avoid triggering a catalyst-related check engine light.
Is there anything I need to do after installing?
Fabspeed notes a valve relearn may be necessary afterward.
How do these differ from Fabspeed's standard C8 cats?
They're not the same units. Fabspeed fit even larger HJS 200-cell catalytic converters specifically for the Z06, made possible by extra room on that platform.
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.
