I removed the center muffler on my 2018 Durango SRT and installed 2 of them (one for each pipe). Should have gotten a 2 1/2" ID model, but was able to get it to work. MagnaFlows amplify the 392's distinct low-level rumble. I didn't notice any rumble at any speed. It's definitely a bit louder though. in the Cabin but not so loud that I can't talk to my wife or daughter in the back seat Cold start sounds best!
