The manifold is a key component of every exhaust system on a naturally aspirated car. It provides an exit path for exhaust gases from the combustion chamber, allowing the engine to breathe and function properly. Milltek Sport manifold pipework is optimized in length and diameter to enable freer-flowing exhaust gas to exit the engine, improving efficiency and increasing performance. The catalyst is bypassed to create a 'Decat' system, which eliminates the catalyst and greatly enhances gas flow and performance by removing the restriction caused by the catalyst. - Optimized pipework for improved exhaust flow - Decat system eliminates the catalyst for enhanced performance - Designed and manufactured in the UK Specifications: - Pipe Diameter: 69.85 - Race Product: Yes - EMarked: No Kit comes with: - Catalyst Bypass Pipe - MSVW284REP - Link Pipes for Milltek Cat-Back System - MSVW285REP - LH Free-Flow Manifold - MSVW282 - RH Free-Flow Manifold - MSVW283 Vehicle Compatibility: - Volkswagen Golf MK5 R32 3.2 V6 2005-2009
