I am gonna have the OEM exhaust mod done in about a week. I've read all the threads and watch all the videos. From hearing the different exhausts on videos clips it sounds like the Perforated sounds less bassy and more high pitched/raspy and the ACM sounds more droney/bassy and less raspy.

Those that have heard both, do you think the same? If so, I think the perforated sounds better. They seem equally loud.

I would like to hear your comments.
