Yamaha YZ 450F Exhaust

Big Gun exhaust for the Yamaha YZ 450F. Slip-on mufflers, full exhaust systems and head pipes in the EVO R, Ballistic and Eco series, fitting model years 2003 to 2018. Slip-on mufflers bolt to the stock head pipe in about an hour, full systems replace the whole run for the biggest gain, and a tuner keeps the fuel right after the swap. Every muffler is built in Corona, California, includes a USFS-approved spark arrestor and ships free over $100. Closed-course use only.
