Big Gun 12-15 Kawasaki KX 450F Ballistic Series Slip On Exhaust

The Big Gun Exhaust BALLISTIC series provides significant horsepower and torque gains while reducing weight compared to the stock exhaust. It features a black powder-coated aluminum muffler housing, a 304 stainless steel mid-pipe, and a machined black powder-coated stainless steel end tip. A removable screen-type spark arrestor is included. This exhaust system is handmade in the USA and comes with a 1-year limited manufacturer’s warranty. Proper tuning with either jetting (for carbureted vehicles) or a fuel controller/programmer (for fuel-injected vehicles) is required to maintain the warranty and ensure optimal performance, as aftermarket exhausts change the air/fuel mixture and can cause the engine to run lean. Regular muffler repacking (every 15-20 hours of ride/drive time) is also necessary to maintain performance and warranty.
