RSR Muffler Bypass Pipes
A pair of muffler bypass pipes for the Porsche 964 Carrera (1989-1994), an optional upgrade for Fabspeed's Maxflo RSR Header/Muffler Kit that eliminates the factory mufflers entirely for a true Cup-car, air-cooled roar. They mate directly to the RSR headers and are built from T304L stainless steel in-house at Fabspeed. They only fit the RSR Header/Muffler Kit in its non-sport-cat configuration, and reuse the V-band clamps included with that kit, so switching back to the standard Fabspeed muffler is easy at any time. Installation is a simple bolt-on with no cutting or welding required.
Frequently asked
Does the RSR Muffler Bypass Pipes fit my 911 Carrera?
This listing is specific to the Porsche 911 Carrera (964). 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 these fit any 964 exhaust?
No, they're an optional upgrade specifically for Fabspeed's Maxflo RSR Header/Muffler Kit, and only in its non-sport-cat configuration.
Can I switch back to the standard muffler later?
Yes, they reuse the same V-band clamps as the RSR Header/Muffler Kit, so converting back to the standard Fabspeed muffler is straightforward.
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.
