I did a resonator delete and had an X pipe put in on my 2018. No drone and when the valves are open it is noticeably louder, pops ect. but I have a bm2 tune with burbles turned up from before the exhaust work. I will probably turn down the burbles. It sounds great and well worth the money. I have a stock muffler btw.
