The factory exhaust system on the 718 generation subdues the mechanical tone of the turbocharged flat-four. The standard catalytic converters restrict exhaust gas velocity and increase turbo backpressure, limiting potential power output. Replacing these restrictive components with high-flow Exhaust Downpipes reduces backpressure and significantly improves turbo spool times. Pairing this upgrade with a Cat-Back Exhausts system fundamentally alters the acoustic profile of the vehicle. We also stock Misc Exhaust Parts, including the necessary clamps and hardware for precise fitment.
