It's becoming fairly common place around here for guys who race their atv's to shorten their exhaust can....I'm wondering if anybody on here has down this or has any info on this? Seems fairly easy to do all that's envovled is cutting about 5" off the can and drilling a couple of new wholes at the end of the tube for the tip and that's about it. So far the only benifits I see is that it makes the bikes hella loud and looks pretty cool to see the blue flame come out the pipe when they let off the gas lol. But that is not enough for me to go hacking on mine lol if it will gain power then maybe!!
