I have heard of people using Marine exhaust hose, like for boat exhaust? anyone had any?

yeah but it looks good and its cheap. as long as you get the right size it shouldn't be a problem. and its about $20 for a foot of the 4 inch stuff. the stuff I saw today was bright blue. you could get 2 or 3 couplings out of a foot of hose
