The Pork Wagon (‘14 Cop Charger)
Given your definition of drone, I will say 'yes', there is definitely drone now, as opposed to before the exhaust mod. When engine RPMs are in the ranges of ~12K-14K and ~22K-24K, the sound of the exhaust coming from the muffler resonates inside the cabin in such a way that it can be felt physically. However, I would like to point out that I never noticed it until I attempted to detect "drone" for this response, so it is not like it will make the CD player skip or make your arm hairs dance.Thanks...I think your answer is fairly comprehensive, especially when you describe the ability to do conference calls without anyone saying there is an issue. Drone is just that irrating harmonic the seems to permeate the cabin at certain rpms. It usually isn't present all the time, just sometimes. The sound of the stock system has gotten better (just shy of 15K), but I still would like something with just a tad more bass. Don't want to wake up the neighbors in the morning, but its okay if they can identify when I pull up when they are awake.
Also, a friend recently rode with me and commented on the increased cabin noise of the exhaust. It appeared to have evoked some sort of visceral response in him, and I fear he might have started rubbing my leg had we continued the trip much longer. Needless to say, I dropped him off POST-HAST!!.
As for the neighbours, I would say I am not waking them up now with my new exhaust because none of them are giving me the stink eye when I see them during the day and chit-chat. However, one neighbour did remark about how I keep odd hours (I work at night, so am in and out at night), so I know she can tell when I come and go.
I suspect it is a lot like the Camaro I used to have in high school which I put some Flowmasters on the last year I was there. When the car approached, you could detect a very low rumble, but it wasn't immediately identifiable as any particular car and wasn't "in your face", so to speak.
Hope this helps,
