I don't haul many nice cars with this truck, I usually use the enclosed trailer when I do that so it is no big deal about the soot. Right now the exhaust is a straight pipe because the muffler fell off when I bought the truck and has covered the underside of the truck with tons of soot. I drove a Lil Red as a daily driver for 4 years and have parted out a few, that is where these stacks came from and they have been laying around for years so I might as well put them to use. This is the latest place I put them, I think that is where they will go and I will sell the steps. How about this set-up?
