I've been really thinking about the exhaust on my 93 5.0 I know that many of you are going true duals, but I had a thought. It sounds like some modifications are needed to make these fit around the tank and other things. Would (or how would) a single 3" pipe help for the exhaust flow? Unless I'm mistaken, we have 2 1/4 stock right? A 3/4" diameter increase would show improvement yes? Let me know some thoughts, pros cons. If it's a good idea, I may do it soon since my exhaust needs work anyway. Thanks guys!
