i kno someone with a WB E-series that was on his 300EX. will this fit on my warrior and if i just geta silencer will i need to rejet it? also is 200 to much for it?

 

it prolly won't just bolt on. put it on b4 you buy it cuz i don't no if it'll fix(i doubt it) $200!! thats way too much for a used pipe. i'd say like a 100 dollars if its in good condition. and yes you will need to rejet.

 

You can buy the correct e-series pipe for your quad from PRM.com for $199.00
The other one won't fit.
