It seems 4th gen long tubes will fit in 5rh gen Rams. There's a set of jmJBA long tubes on local marketplace for $650. I've been reading that they have fitment issues in 4th gens, but it seems most of the complaints are due to not coming with a y-pipe, which doesn't bother me. Will just have local exhaust shop make one. I know he probably didn't pay $650 for them. Should I offer $550 and see what he says? Pretty sure my drivers side manifold is cracked. Already had passenger side replaced under warranty, but I'm not under warranty anymore.
