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.
Can I reuse my factory tips?
Only on S and non-PSE models. Fabspeed notes that PSE-equipped and GTS models require Fabspeed's own tips rather than the factory ones.
What sound change should I expect?
Fabspeed describes a throatier, deeper exhaust note throughout the RPM range for improved sports car sound.
Is installation just bolt-on?
It is a bolt-on installation, though Fabspeed notes minor cutting is required at the factory exhaust break point.
What are the power and weight numbers?
Fabspeed lists an 8 wheel horsepower gain and a 16 kg weight saving versus the heavy factory OEM mufflers.

Reusing your factory tips is only possible on non-PSE, non-GTS 957 S models. PSE and GTS cars must use Fabspeed's tips.

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.

Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
