It’s interesting to hear the models that others consider loud. Just for comparison sake, my 1998 Echelon is the quietest of our group of boats. It has the Primex mufflers (I think) from back in the day....though I’m sure the baffles are shot by now. Followed by In order of loudness: 2012 TXI, 2011 LXI, 2006 LXI, and then the obnoxiously loud 2008 MC prostar. It’s unreal how loud that boat is.
