white Bros E series

[300ex_rida]

Is the white brothers e-series a good pipe for the 300ex? Does it give it a lot of bottom end power? Does it make or go faster? Also do u have to rejet it . If so what size jet should i use. If you think there is another pipe that is better tell me thanx.

you don't have to rejet just play with the disks till it works good with stock jetting, also it gives it more acceration not speed, if you need more speed just got one tooth more on the front sproket and she'll pull. also it has gain a little on the bottom but the must is noticeable on mid to top.
BTW this is for a 400ex
