Fabspeed HJS Sport Catalysts for Lamborghini Aventador LP700-4 (2011–2016)

These HJS sport-catalyst assemblies replace the original LP700-4 catalyst sections on the specified USA-market exhaust layout. Integrated oxygen-sensor and EGT ports must match the car before installation. Fabspeed Motorsport, based in Fort Washington, Pennsylvania, develops exhaust systems, air intakes and ECU tuning for sports cars including Porsche. Its development work uses dynamometer testing, road evaluation and racetrack testing.
