I have a YFZ450 and this winter im doing some serious mods to it. Now i know i should be asking this in the Performence Mods section but nobody replied. Anyway, i am already putting on it the ATV PRO Power Pack, Changing it to a 480 with a bore kit, putting a White Bros Carbon pro race exhaust, Tag X5 bars with pad and vinyl cover, ct racing graphic kit(blue) and Ac Racing bumper.
Do u think i should get another pipe?
What tires should i use? I mostly ride in trails and dirt tracks..
What can i put on it to make it even faster?

Oh and i have a nerf bars..

 

if you just ride trails and some track... then why waste the money and loose reliability?
the pipe will be fine i supose, dont know much about the WB.

 

Thank you for your info...
