grinding welds on OEM header?

[mineralgrey01gt]

what does this mean exactly and what gains will i get from this? Ive read it numerous times and was wondering about it

if you pull off your header pipe and look where it connects to the head there is a ring of welds on the inside of the pipe. You can smooth those down and allow better air flow.

Basically your doing a port of your header pipe

haven't done it yet myself, i plan on riding a good bit starting tomorrow.

They said it opens up the exhuast by .125, just have to give a try and see what happens
