991.2 GT2 RS Valved Sport Cats
Valvetronic sport catalytic converters for the Porsche 911 GT2 RS (991.2, 2018+), replacing the restrictive OEM ceramic 700-cell cats with German manufacturer of the high-flow catalytic converters Fabspeed fits in its sport cat products. German-imported 200-cell HD tri-metallic cores that flow up to 93% of a straight pipe. Fabspeed pairs them with UK maker of the aerospace-grade exhaust valves Fabspeed uses in its valved exhaust systems. vacuum-actuated exhaust valves sized at 76mm, larger than the factory 60mm valve, while fully retaining PSE function. Tested with Fabspeed's ECU tune, the combination adds up to 75 whp at 7200 rpm and 108 ft-lb of torque at 3200 rpm, with quicker turbo spool and throttle response even without the tune. No catalyst-related check engine light. Bolts directly to the titanium OEM centre muffler, with a simple 4-clamp installation.
Frequently asked
Does the 991.2 GT2 RS Valved Sport Cats fit my 911 GT2 RS?
This listing is specific to the Porsche 911 GT2 RS (991.2). 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.
Do the headline power gains require the ECU tune as well?
Yes, the 75 whp and 108 ft-lb figures are from Fabspeed's testing with the sport cats and their ECU tune together, though the cats alone still sharpen turbo spool and throttle response.
Does this keep my factory PSE function?
Yes, it's fully compatible with Porsche Sport Exhaust and keeps that functionality intact.
How long does installation take?
It's a simple swap, just 4 exhaust clamps to remove and replace.
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.
