Ahh okay that makes sense, I mostly drive highway trips to my college 2-3 times a week so its nothing crazy, ima warm it up and do what you said tonight and see what happens. That would make a lot of sense if one of my mufflers is bad. What are the downsides to having a bad muffler? If any at all.100% can tell you one of your mufflers is bad.
If you can go under when it’s cold and hammer fist then I bet you will find one at least has a loose fin inside.
I bought my 11 RTClassic in April with 104k on it.
First thing I noticed was the same sound after revving is that metal vibration sound when you let off and the engine returns to idle.
about the gurgle. How often do your drive and where. Mostly city? Cold climate? Short trips parked outside?
if it were me I would get an open stretch let it warm up then from a few rolls go wot and blow that stuff out. My hunch it’s condensation in the exhaust and probably why that fin in there is loose.
