necking down after collecter?

Not the popular opinion, but I don't think there is such a thing as too big in that distance from the merge to the mufflers. One 3" pipe is similar in area to two of 2"pipes, but 2 of 2" pipes has ~33% more pipe skin... so if you installed a PAIR of 2s on each side, you'd end up with a lot pipeskin,er radiating area, and your muffler would not have to work so hard. lol. But I'd run about a foot and a half of merge-sized pipes first.So then.............
