My only complaint is a slight drone between 2500 and 3000 rpm, but it's not unbearable. Love the way it sounds

I did extensive research on stock muffler replacements for my 2019 Ram 1500 (5.7L). The main concern for most V8 owners is drone. I had a Flowmaster picked out but it was recommended on forums to go with this. I took the plunge and bought it. It has a solid deep tone that says yeah I have a V8 Hemi but not loud enough so people think I am the jerk in the neighborhood. It has no drone (yes, I ran it around 1500 rpms with MDS 55mph) but you could hear the deep power sound when you step on the pedal. Worth every penny and gives me what I want (as this is my daily driver).
