Valved Supersport X-Pipe Exhaust System
This valved supersport X-pipe replaces the SVJ's factory muffler, which Fabspeed found oversized and restrictive for the car, cutting 21 lbs while opening up exhaust flow. It uses Helical 76mm vacuum-actuated valves built from silicon carbide and investment-cast stainless steel, the same valves Lamborghini, Ferrari and Porsche fit to their own OEM systems, so they're built to resist the leaking and rattling that cheaper valves are prone to. Because it's a Installed after the catalytic converters, so the factory emissions equipment stays in place system it stays emissions legal in all 50 US states and worldwide. Professional installation is recommended, since fitting it means removing the one-piece rear bumper.
Frequently asked
Does the Valved Supersport X-Pipe Exhaust System fit my Aventador SVJ?
This listing is specific to the Lamborghini Aventador SVJ (LP770-4). 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.
How much weight does the SVJ system save?
21 lbs, mostly from the rear of the car by replacing the oversized factory muffler.
Are the valves reliable?
Fabspeed uses Helical 76mm vacuum-actuated valves made from silicon carbide and investment-cast stainless, the same valves Lamborghini and Porsche use on their own OEM exhausts, built to a higher standard than the cheaper valves prone to leaking and rattling.
Will it trip a check engine light?
No, Fabspeed says it's a straightforward bolt-on with no check engine light and no emissions issues.
Is professional installation required?
Professional installation is highly recommended, since fitting the system means removing the SVJ's one-piece rear bumper.
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.
