Show original supplier description
The Milltek Large Bore Downpipe and Hi-Flow Sports Cat (SSXVW765) is a high-performance exhaust upgrade engineered for the Volkswagen Golf Mk8 GTi (245ps Non-GPF, North American Models Only, 2021-2024). This downpipe features a significantly larger 94mm (3.7-inch) ID turbo outlet that transitions to an 80mm (3.15-inch) diameter pipe. It integrates a 200 CPSI NO CEL Race Cat, designed to enhance exhaust gas flow and improve engine performance and sound without triggering a check engine light. The system is constructed from premium type-304 aircraft-grade stainless steel, known for its durability, anti-magnetic properties, and resistance to discoloration. Mandrel bending ensures smooth, unrestricted gas flow. This downpipe is explicitly stated to fit with Milltek Cat-Back systems only. It is designated as a 'Race System' and is not ECA approved, indicating it is intended for off-road or track use where permitted. Milltek Sport has over 32 years of experience in exhaust development, with all systems designed, developed, and manufactured in-house in the UK. They utilize increased bore sizes to ensure ultimate performance gains without compromising mid-range torque.
