Like most exhausts, the most gains are at the top end. There is some low and mid range improvement but not proportional to the higher range. Once you finish your intake/exhaust upgrades an ECU tune will help improve the low and mid-range performance, amongst other things.
I definitely agree with this. It sounds a lot better imo. When you gas it, it's nice and deep. Otherwise, it sounds relatively tame. Bluestyle55's video helped a lot, as well as TROOPER's video. I think you'll love it. At times for me, I wished it was louder. Today though, the exhaust sounded perfect. Must be the cooler weather :-). Please post pre/post dynos when you get a chance. Congrats and good luck!
