Since I am thinking in the next year to go with a 3.4L swap I am looking into a cat back exhaust system and maybe a high flow cat or omitting the cat since I don't have to pass emissions here. Anyone know of a bolt on deal without custom fabbing something? I have a slight exhaust leak so it would be good to clear that up to. I am trying to validate upgrades when I need to replace things anyway. Thanks as always this forum is very helpful.
