Got her installed today. Haven't took flipper out to test the pipe out just rode down the road a couple of times. Flipper seems to be responding good from the little ride I gave her (wound out 1st).
My first impression is quiet as HELL. Compared to my pipe it sounds stock at idle. When on the throttle it gets louder. It has a different tone in general though. Mine was a lot deeper eat little children type roar. This pipe still sounds mean but in a different kinda way. Haven't quite figured it out yet with the minimal ride I took.
Jury is still out whether I like it or not. I definitely love the look.
