Question. I'm looking at stacking an Edge on top of my TST. How much smoke am I looking at? I'm one of the few that could care less if my truck smokes. Really, I'm serious. The reason I'm asking is it something I'm going to need to be concerned with living in CA? OK. I know that answer. But am I looking at so much I can't drive it like I want to or am I going to have to baby it where ever I go. I've heard that this setup actually helps temps a bit, true?
