I bought a brand new raptor 350 last friday and been riding but already eager to see what upgrades will do for me....I was looking on rockymountainatv.com and found these few things that i see talked about quit a bit.



K & N Jet Kit -- Doesnt give jet sizes so which do i go with?

Yoshimura TRC Comp Series Silencer
Fits: 2008, YAMAHA, RAPTOR 350


Will the slip on with the jet kit improve it enough to spend the 400.00 on or is it a waste of money?

It will give you a noticeable increase in power, but the HMF slip-on is just as good as the Yoshi and alot less expensive for $220.
