FabSpeed Lamborghini Aventador SVJ Valvetronic Supersport X-Pipe Exhaust System



The Fabspeed Lamborghini SVJ Valvetronic Supersport X-Pipe replaces the factory muffler that is very restrictive and oversized for the vehicle. When diving into the SVJ our R&D team noticed how large the factory muffler was on the SVJ and new it need improvement in both air flow and size. We shaved off 21 lbs with our new Valvetronic Supersport X-Pipe and improved exhaust gas flow resulting in a different exhaust note that really brought out the sports car sound.
