450r exhaust

[dabram86]

Doing some research on 450r exhaust was wondering what full exhaust system do you guys think has the most Horse Power and overall performance increase

almost any aftermarket exhaust will be better than stock,louder too.:)

my buddy has a curtis sparks full system for his 450r and the torque increase was awesome. stock, the motor feels like it has no bottom end power, but with a pipe it has tons. it pulls hard from bottom to top end with it. its really loud, so if noise is an issue dont buy an after market pipe.
