Frequently asked
Which cars does the Valved Supersport X-Pipe Exhaust System fit?
Fits your Porsche 991 Turbo. Fabspeed lists this piece for: all Porsche 991 Turbo / Turbo S twin turbo 3.8L vehicles (2013-2016). 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.
What's the difference between valves open and closed?
Closed routes exhaust through the quad-resonated X-pipe for a smoothed, sophisticated tone; open bypasses it for an aggressive, unfiltered scream with crackles and pops on deceleration.
What's the difference between the Street and Race options?
Street keeps HJS sport catalytic converters for emissions-legal street use; Race uses cat-bypass pipes for maximum flow and is intended for closed-course use only.
Do I need any extra parts to control the valves?
If your car wasn't factory-fitted with PSE, you'll need Fabspeed's Valve Controller Kit to open and close the valves.
What valves does the system use?
Aerospace-grade Helical valves from the UK, the same Tier 1 supplier used by several OEM supercar makers.
Which option should I choose?
Choose Street if you want to keep HJS sport catalytic converters and stay emissions legal on the road; choose Race for cat-bypass pipes built for maximum flow in closed-course competition only. Tip finish (polished stainless or satin black) is purely a styling choice and doesn't affect the exhaust's performance or sound.
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.
