Jump on your Grom and have a blast with the new and improved Vance & Hines Hi-Output Hooligan exhaust system, now equipped with PCX™ technology. Our innovative PCX™ technology integrates a chambered high-flow catalyst that boosts torque and horsepower over previous generations of our Grom system, while also making it 49-state emissions compliant for the street. Hand TIG welded and constructed of 304 stainless steel with spring-clip joints and a brushed finish, the Hi-Output Hooligan has the looks of a GP pipe and gives the Grom a healthy bark to level up the fun!
Please select your ride so we can be sure we get you exactly what you need.
