[troutman561]

sorry to sound stupid but whats the best head pipe for the 400, i have a fmf power care 4 slip on, do i just use the head pipe made for the slip on, or is there a stand out one that does even better

you really don't have too many options that will fit that pipe. most recommend a fmf powerbomb

The stock head pipe is suppose to be better than most after markets head pipes. They had a head pipe shoot out in dirt wheels and out of 9 pipes there was only one head pipe that was better than stock. And the one that was better was only better by 1 horse
