One of the best buys I have found for a new Magnaflow 16633 catback exhaust has been from WunderCarParts (1-888-986-3373) for around $400 shipped. Probably a bit more now? It was a group buy on here at one time, but apparently it has been removed as an old post? Anyway, you can call them and ask for the Crossfire forum price. You won't see the lower price on their web page.
