Frequently asked
Does the Center Muffler Bypass X-Pipe fit my 911 Carrera?
This listing is specific to the Porsche 911 Carrera (997.2). 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.
Will this drone on the highway?
Fabspeed describes a refined, non-droning tone without PSE or with PSE valves closed; opening the valves on PSE cars brings a much more aggressive, race-like note with pops and crackles.

Fabspeed's testing showed peak gains of 12 whp and 20 Nm of torque.
What does it replace?
It's a direct bolt-on replacement for the factory centre muffler.
Does it work alongside the factory side mufflers?
Yes, Fabspeed says it pairs well with either the factory side mufflers or their Maxflo Performance Side Exhaust System.
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.
