Hey John, thanks for the compliment!
I've only had the exhaust on for a little over a month now but absolutely love it so far. It's got a nice deep growl when you give it some gas and seems only slightly louder at idling than the stock exhaust. When cruising at around 2k rpms, its hard to notice much of a noise difference and its fairly easy to carry conversations in. On the flip side, when you step on it a little to pass somebody or even just to accelerate, it pauses the conversation for a little with a bit of a mean growl.
Overall, haven't noticed much drone if any at all and for cruising with low rpms it doesnt seem too loud either.
Love the 4' exhaust tips as well, gives it a much beefier look to fill out the gaps. Also worth mentioning, it's just the axleback, not the whole catback.
