Larry, It has hooker mufflers on it from when Don had his 318 in place. He had 1 3/4 exhaust with very small headers. He now has Hooker super comps 2 x 3.5 inch. The exhaust isn't sealed all the way yet. I cut off his exhaust header flanges and stuck his pipe up inside the 3.5 collectors. It will eventually have 3 inch to the mufflers. Don will take his car home and do little projects to his car when he is done with his term in Hi. He will also be doing his tire and rim choices, little things like that.
