Anybody got the motoblue exhaust on a 7.3? They seem to have a decent price and I was wondering about the sound.
Low end grunt I think is the difference between 4" and 5" exhausts but what also matters is the downpipe size.Not to hijack the thread but is there really any difference between the 4" and 5" kits other than price and size. I am looking to put some new exhaust under my truck and was curious what would be better
