its not that bad unless you have alot of power and blow alot of black smoke, the only time mine got covered in soot was after i washed it so i let it run as i washed it, i never got soot after it rained but you could do like said above and drill a hole or two at the bottom to let the water drain out, you could go with flat tops and put tractor flaps on it?

i know people who have had lower EGTs with stock straight piped exhaust. you don't put exhaust on planing on getting better MPG, if you do you will be very disappointed. the stacks sound good from the outside but get very annoying in the cab. i cant wait to remove my stack.
