There is not a single product on the market that can compete with the style, performance and “perfect” sound of Vance & Hines Big Radius 2-Into-2 PC Exhaust for the 2011 Yamaha XVS1300 Stryker. By incorporating our proprietary Power Chamber technology we have revolutionized metric cruiser exhaust design by giving you increased mid-range power and less noise. To be honest, we wouldn’t call it noise as much as the perfect sound.
