Need opinions about stacks. I am thinking considering putting stacks on my truck. I have a 4" cat-back system exhaust now. One reason I am considering stacks is in the past depending on the lake I put my boat in, sometimes I to back in to the point that my exhaust would be in the water. I had to keep the engine wound up to keep the exhaust pressure going. So what I am asking is I ahve seen kits that going from the turbo and kits that get rid of the cat. I what to stay legal and keep the cat. Don't want a loud truck but I would like to know is how loud this might be when the cat is still in place and there is no muffler.
