PowerBomb Exhaust Header 06-21 Kawasaki KLX 250 S SF CAMO 300 R - FMF 042385

The FMF Racing PowerBomb 042385 header is engineered to deliver significant performance enhancements for four-stroke motorcycles. Utilising FMF's patented PowerBomb module, this stainless steel header optimises exhaust flow by strategically placing an expansion chamber at a critical point. The result is increased horsepower and a notable improvement in throttle response, with flow gains approaching 10%. The PowerBomb design also functions as a pre-muffler for reduced sound output and accommodates either stock or FMF mufflers for versatile setup options.
