Stainless Steel Valved Cat-Back Exhaust System
Valved cat-back exhaust for the Chevrolet Corvette C8 ZR1X (2025+), built around Fabspeed's cast A crossover pipe joining the two exhaust banks into an X shape, smoothing flow for a fuller, balanced tone. and mandrel-bent stainless steel piping, with Helical UK valves wired into the factory exhaust-mode switching. Open the valves and the ZR1X gets a sharper, higher-pitched wail through the top end; closed, it drops back to a quiet, drone-free cruise indistinguishable from stock. All factory drive modes and Z-mode functions stay intact, and the system saves 20 lbs over the factory exhaust. Bolt-on installation with no fault codes. Excludes EU-spec cars.

Frequently asked
Which cars does the Stainless Steel Valved Cat-Back Exhaust System fit?

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 the valved mode affect the car's other drive modes?
No, Fabspeed says all factory drive modes and Z-mode functions stay fully intact, the valves just plug into the existing exhaust-mode switching.
How different is it in quiet mode versus loud mode?
In quiet mode it's drone-free and about as loud as the factory exhaust; switch to loud mode and you get a much more authoritative idle and a higher-pitched wail at higher rpm.
Does it trigger any fault codes?
No, Fabspeed guarantees no fault codes since the valves are plug-and-play with the factory electric actuator modules.
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.
