what should i look for when searching for a performance pipe?

Make sure it's ok for off road, noise and spark wise, if that's where you ride.
Be prepared to fool with your carb jets a few times if the exhaust is less restrictive than stock or whatever's on there.

Not sure what or how much advantage there is to a pipe change.

I like stock stuff, but I'm also not looking to win any races either.
