I'd say it's more that I'm going from 3" to a like 6" chamber and then back down to a 3"...now it's just straight 3". For those curious though, I'd still absolutely do it again to feel a before and after before considering paying aftermarket prices. Find a set someone else already gutted if possible and/or buy used aftermarket downpipes whenever possible.
