The factory exhaust system heavily restricts gas flow and mutes the aggressive acoustic profile of the 300+bhp B48 engine due to strict factory particulate filters. Unlocking exhaust velocity right off the turbocharger with high-flow Exhaust Downpipes drastically reduces backpressure and sharpens throttle response. Transform the acoustic note of your hot hatch with a high-flowing Cat-Back Exhausts system, an emissions-compliant GPF-back exhausts setup, or complete Tubo Back Exhausts. Bypassing restrictive factory filters with GPF deletes yields maximum gas velocity, while aggressive Exhaust Tips give your rear diffuser an imposing look, supported by our range of Misc Exhaust parts.
