OK, so I chickened out on the Super 40. I was getting a little nervous reading this thread and others, and then when the shop called to let me know it was on (not welded) and was really really loud and sounded like crap, I went with a mangaflow instead. It sounds great, and probably more of what I was after. can't really hear it at idle, but sounds great at 15-2500 and sounds bad *** at about 4500!

Thanks everyone, now for an intake
