Milltek Hi Flow Sports Cat Downpipe with OPF Bypass, a fantastic exhaust modification for your Mk8 Golf R that delivers outstanding performance when used as a stand-alone upgrade or paired with the Milltek Mk8 Golf R OPF Back System.

Eliminating the factory OPF and upgrading the stock catalytic converter provides significant benefits in terms of airflow and exhaust sound. By bypassing these restrictive components, back pressure is substantially reduced, leading to an incredible exhaust note at an affordable price and unlocking greater tuning potential compared to the stock system.

Milltek Sport exhausts are crafted from high-quality type 304 aircraft-grade stainless steel, which is anti-magnetic and less susceptible to discolouration than other manufacturers' stainless steel. This premium material is used throughout the entire construction, including pipework and silencers. Mandrel bending ensures full-flow bends for improved gas flow, and the exhaust systems feature an increased bore for ultimate performance without compromising mid-range torque. Every Milltek Sport exhaust is designed, developed, and manufactured in-house in the UK.

*Only compatible with OPF-equipped vehicles.
