Hi, sorry it took so long to get back to you. The exhaust sounds fantastic. I mean even at start up it sounds so good. The only drawback is there is a drone at cruising speeds (6th gear highway speeds). But all in all I am very happy with it. Even with the drone the radio and bluetooth are easy to hear. It is especially fun and sounds great on 2nd thru 4th gear... I am not disappointed that I had it installed.

How does that GMPP exhaust sound?
