Thanks! Matt, it is a $20 Summit Glasspack- and it flat sounds awesome! I am planning on ditching my Diamond muffler for a Dynomax 4" Race Glasspack soon. Summit only makes their 12" glasspacks up to 3". Fortunately Dynomax makes one that is 12"s that is 4". The truck sounds like a tractor trailer and a Cummins rolled into one when you are accelerating. A nice deep bawaaaaaa sound with a hint of GMX whistle. It was a complete surprise. In fact it sounds so good my wife has told she wants all her trucks to sound like that! I guess she has diesel fever now!
