It is plenty loud enough for me. Has a great bark on a cold start, calms down nicely, and has an aggressive sound when on the throttle, but quiets down with zero drone when just cruising. For me, it is blissful perfection. I haven't towed my boat with it on yet but look forward to it. On longer trips, the Borla 40393 muffler replacement I had on there got irritating/drony when towing. Not too bad though, and fine on shorter trips, but I mostly fish 2-1/2 to 3 hours away.
