I'll either be going with the Pypes Violators or the MAC mufflers over on AM if I buy new. I really like the sound of the MAC setup, but I like the price of the Pypes better. This is assuming I don't find a good deal on something used off of eBay. I've been watching both Flowmaster, Pypes, and the MAC stuff. Don't see much MAC stuff come across, but Flows and the Pypes are pretty common.
