White brothers e series

Hey guys

I just ordered a white brothers e series pipe and I want to know if it really is going to help the performance of my quad.








Yellow 2001 400ex
DG Alloy nerfs
DG A-arm and swingarm skids
K&N filter & modified airbox lid
Renthal bars
PRM bumper
WB e series on the way

Its going to help over the stocker but don't expect that much of a difference with the pipe alone...maybe 2-3 bike lenghts over a stock 400ex in a 300 foot drag.. if that

It will sound much better tho :D

you need to re-jet or else you won't be very impressed
