The MagnaFlow Volkswagen Golf R Sport Series 19165 enhances your 2015-2017 Volkswagen Golf R 2.0L with an aggressive character that will help you stand out from other Volkswagen Golf Rs you meet on the street. With its 3 inches. Diameter quick-flow mandrel bent main piping that passes through 1 straight muffler before terminating in a quad split rear outlet with 3.5 inches. Polished welded tips with cut and bent double wall angles, this dyno-proven Volkswagen Golf R exhaust system refuses to be ignored. As such, 19165 is tuned to produce our loud, resonant exhaust note at aggressive exterior and moderate interior sound levels, so please check to ensure compliance with local noise regulations. The system's cat-back design replaces all of your stock exhaust components from the rear catalytic converter. Extensive 3D scanning and CNC precision robotic manufacturing techniques are used to ensure your exhaust system fits perfectly with a simple do-it-yourself installation process. Durable, corrosion-resistant 19165 stainless steel construction is backed by MagnaFlow's Limited Lifetime Warranty.
