I am happy with the tone. To me it’s pretty much perfect and what I was looking for. It’s not obnoxiously loud and yet has a mellow & deep rumbling every one likes. Haven’t noticed any real drone. I’ve thought I heard drone a few times just for a fleeting moment but it quickly goes away as the rpm change. I think it’s when I’m off the throttle and in 10th at a low speed. Perhaps when the cylinder deactivating is happening. Not sure. Somewhere I read that you could hear the CD kick in/out more easily with a aftermarket muffler but I have not noticed that at all. However I still have the OEM resonator on it. Driving on the interstate today between 80 and 55, I didn’t notice any drone either.
