More than just individual head pipes, Power Duals integrate an exclusive Vance & Hines Power Chamber hidden behind a contoured heat shield that generates more horsepower and torque than stock. This new right-side design eliminates the heat issues on the left side for the passenger, routing hot exhaust gases below the footpeg and protecting vital engine components and side covers from heat damage. Power Duals are fitted with oxygen-sensor ports, allowing for a seamless power upgrade from stock. Add the Monster Oval slip-ons for twice the internal volume of standard slip-on mufflers. Monster Ovals are encased in blue proof formed heat shields with billet machined end caps in either chrome or black.
