Show original supplier description
The Milltek Sport SSXVW678 is a performance exhaust system, specifically a Race System designed for the Volkswagen Golf Mk8 GTi (245ps models equipped with OPF/GPF). This GPF/OPF-back system features a 3.15-inch (80.00mm) pipe diameter and is crafted from T304L aircraft-grade stainless steel, known for its anti-magnetic properties and resistance to discoloration. It includes a rear silencer bypass (Race Version) and dual outlet pipes, culminating in two polished GT-115 tailpipe trims, each measuring 4.5 inches. The mandrel-bent pipework ensures full-flow bends for optimal gas flow, and the increased bore size contributes to ultimate performance without sacrificing mid-range torque. Milltek Sport emphasizes genuine performance gains, sharper throttle response, and a substantial weight saving over stock exhaust systems. The product is designed, developed, and manufactured in-house in the UK, backed by over 40 years of continuous exhaust development expertise. The company states that their stainless steel exhausts offer a "genuine performance edge" and a "truly awesome" sound. This particular system is designated as a "Race System (Loudest)" and is intended for OPF/GPF equipped models only. Please note that De-cats, Sports/Race Cats & GPF Bypass Deletes are for Motorsport Use Only. Installation is described as straightforward for a competent DIY mechanic, though professional assistance can be sought.
