Side Muffler Bypasses
A direct bolt-on replacement for the heavy, restrictive factory side mufflers on the 992.2 Turbo and Turbo S, cutting 18 lbs and adding a dyno-verified 8 hp and 12 lb-ft at the wheels. Built from T304L stainless for long-term corrosion resistance, the system retains full factory exhaust-valve operation and doesn't touch a single emissions component, so it's 100 percent CARB-exempt cat-back and typically has no bearing on unrelated warranty coverage. Fitting it means removing the rear bumper cover, heat shields and both factory side mufflers, so professional installation is recommended.
Frequently asked
Which cars does the Side Muffler Bypasses fit?

What does the price include?

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.
Is this legal for a road car?
Yes. It's a true cat-back exhaust that doesn't touch any catalytic converter or emissions equipment, so it's 100% emissions legal and CARB exempt.
Does it affect the factory exhaust valves?
No. The system retains full OEM exhaust valve functionality, so the factory valve behaviour and drivability carry over.
What's involved in fitting it?
The rear bumper cover, heat shields and both factory side mufflers need to come off, so Fabspeed recommends a professional install.
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?
