Tony, I've got a guy coming this weekend with a great digital vid, I'll send you an e-mail with the Macs and the bullets. And I don't have cats...
Also, I like the DI/DO, but I just like the chambered exhaust note. I'll lose a few HP to keep a musclecar sound. One thing I have considered is putting two Sweet-Thunder chambered mufflers under the car at about 16" long. I like the sound of them, but I am concerned about the decibels again. I simply can't see getting two chambered mufflers under the car to look decent and not scrape or tear off. I would love to put the Mac's back under the car in the center because they sound bad *** but I can't get them there for the gas tank.
Justin's setup sounds good, as I've got two guys down here in the south running a 3.5" single. They both have a very loud systems, one with a Borla XR1 and the other running a Dynomax Ultraflow round.
As I said earlier, when I moved the bullets to the front of the gas tank with pipes running to the pumpkin, the sound deepened, but still nothing compare to the Mac's.
