I plan to get a White Bros E-Series pipe for my quad as soon as the factory warranty expires. According to a file I got from thier website, rejetting is not necessary if all you add is the pipe. If you want to check out their website for all you want to know about the e-series for the Warrior, send me an email and I'll forward the link.

 

The White Bros pipe bolts right on. Nothing necessary, it fits at the split where the old rear half joins and the back bolts on where the other one did. i don't see why a person couldn't put it on and then put the factory one back on if there is a problem.

 

Yeah, I will probabally just get the pipe. Are you sure I don't have to rejet it? Do I have to put holes in the airbox?
