Ok, did a search and couldn't find any discussion on the benifits of installing a 4in exhaust. I have a price for the entire stainless system and now I have to justify the cost with an mpg gain. I'm an old street rodder from the 60s and I know the benifits of duel exhaust, mostly performance and sound(did't care about mpg then), but it was much cheaper then. This post should not put a debate about manufacturers, I want to know how it increased your mpg!
