FULL SYSTEM X3 MX RACING TITANIUM YAMAHA YZF450 03-05 LOW BOY

"Both the header pipe and silencer are fabricated from titanium, providing extremely low weight as well as high strength. The silencer is finished off with a carbon fibre end-cap and is easy and straightforward to repack. Some applications give you a choice of standard or low boy options. Low boy systems have been specifically developed to produce more low end torque, ideal for supercross and tighter, more technical tracks."
