Gonna get some flack over this, but I bought this 04, 5.9 that someone put Banks Power 6 pack in it, 5" pipes all the way back; they spent some cash on the exhaust and breather and all, but it's just too loud to suit me. Truck runs like a scalded dog, and young high school boys drool when they hear me go by. I just need to quiet it down some. EWhat's my best options? It has a big bullet shaped muffler (don't think it's a cat. conv) right in the middle. Hate to sound ignorant, but been a Ford man for years, new to the Cummins. Just need a little more quiet.
