you might want to go ask around some of your local exhaust shops. at my buddy's shop he has a whole stack of stock exhaust systems (take-offs) he keeps for when dealerships get trade-ins that have duals...they want to go back to stock exhaust so they can sell it easier. he did just that w/ my truck when we put duals on it, he cut the price a little bit if i let him keep my stock system. most of em would probably do your trade too, i know my friend would.
