Im buying a new yfz 450 at the end the febuary. I think im going to get the gytr's aluminum muffler and header pipe, i also think im getting there air filter and jet kit, i will take off my air box lid, how much better will these mods make the 450 run and how much horse will it add, also does the cam mod do alot and is it pretty easy
thanks

I have the very same mods. but I chose Uni-Filters..... You wont belive its the same bike...... NO JOKE!!!!!!!!!!
If you just pull the airbox lid, pull the baffle out of the stock exhaust and rejet you wont belive the diff...
The bike is a ROCKET

Careful with GYT exhaust.

Ours dysintragrated in minutes.

I run the white Bros e series 96 and it's it's supurb.

It's tuneable, has spark arrester, well built.

HMF has a new quiet yet performing line coming out Very soon. Worth a look , worth a wait too.

and take the time to dial it in....
