MILLTEK SPORT VOLKSWAGEN GOLF R LARGE BORE DECAT DOWNPIPE & GPF BYPASS (MK8)

The Milltek Decat Downpipe with OPF Bypass is an excellent exhaust modification, whether used as a stand-alone upgrade or paired with the Milltek Mk8 Golf R OPF Back System.

By removing the factory OPF and catalytic converter, you’ll experience significant benefits in terms of airflow and exhaust sound. Bypassing these restrictive components dramatically reduces back pressure, resulting in an amazing 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 Milltek Sport exhaust systems feature an increased bore for ultimate performance without sacrificing mid-range torque. Every Milltek Sport exhaust is designed, developed, and manufactured in-house in the UK.

*Only compatible with OPF-equipped vehicles.
