    The HammerHead Performance 150cc Exhaust Kit comes complete with a head pipe, aluminum muffler with a laser-etched HammerHead Performance logo, metal intake, upgraded UNI air filter, the pilot and main jet for the carburetor, as well as an anodized billet end cap to match the color of your go-kart.

    This kit is guaranteed to retrofit any Hammerhead 150cc go-kart on the market and will probably retrofit most other brands of 150cc go-karts or other similar GY6-150cc engines that are mounted the same way as the Hammerhead 150 engines such as American SportWorks, Trailmaster, Carter Bros, Kinroad, SunL, Massimo, Blade, Roketta, etc...

    Not only does this kit sound very throaty and clear, but it is guaranteed to increase your acceleration power, top end speed and overall performance.  You will be very pleased with what this kit will do for your kart's performance and looks.

    **Please note that it is up to the purchaser to figure out the best combination of jets for the carburetor**
