Frequently asked
Does the TrackTec Valved Bypass Exhaust System fit my Cayman?
This listing is specific to the Porsche Cayman (981). 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 it drone with the valves closed?
No. Fabspeed says with the valves closed you get the familiar sporty, refined Maxflo tone with no droning.
What happens when I open the valves?
Exhaust travels unrestricted through 48mm dump tubes bypassing the mufflers, giving a burbling, crackling, thunderous roar on throttle, according to Fabspeed.
Do I need anything extra to control the valves?
If your car doesn't have factory Porsche Sport Exhaust (PSE), Fabspeed says you need their Valve Controller Kit to operate the bypass valves, so choose that option when ordering.
How much power and weight does it change?
Fabspeed's figures show about 15 whp and 26 Nm of torque gained at 4000 rpm, and the system saves 2.7 kg from the rear of the car versus the full OEM exhaust.
Which option should I choose?
Check your center console for a button with an exhaust-tip icon. If it's there, your car has PSE, pick that option. If not, pick Standard Exhaust and Fabspeed includes a valve controller kit so you still get driver-controlled valves.
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.
