If you like the swivel end as opposed to the fixed hook for ease of installation, replace those rusty old exhaust springs with Helix Racing Products swivel springs. They make your bike look better and eliminate worries of your exhaust falling off when landing a jump. Springs should be measured when they are off of the motorcycle, and the length measurement should be taken from inside hook to inside hook when off of the vehicle. For a correct fit, exhaust springs should not be extended more than 20 percent of their free length.

FMF Racing's MegaBomb headers deliver more useable power and can lower noise levels by as much as 1.5dB. FMF Racing MegaBomb Plus header pipes provide all the awesome benefits of the originals, along with updated resonance chamber technology for better performance. The patented header design allows exhaust gasses to expand, cool, and ramp back up at a higher velocity, resulting in torque gains typically associated with longer headers and the healthy over-rev of a short header. When combined with an FMF Racing slip-on muffler, gains of up to 3 hp can be achieved with a stock motor. FMF MegaBomb Plus headers are best suited for Motocross, Supercross, and GNCC-style riding where more bottom to low end response is desired. Choose the MegaBomb Plus headers designed for your dirt bike.
