Exhaust options are extensive. Are you looking for power, sound, looks, clearence, orall of the above?
It seems like some guys scrape the Big Shots. I guess every pipe could be scrapped depending on how hard you ride, one guy recently posted about hitting the stock headers. He was dodging some on comming traffic but he says he did it non-the-less.
I have ridden my Warrior pretty darn hard and I have never hit my exhaust. I only weigh 150 though, I dont lower my Warrior much when i am on it. If you put air ride or one of the Lowering Links on your Warrior, your pipe selection will be less I imagine.
Just some things to consider....
