ok i recently got a 1989 bronco full size due to the problems of having one truck to 4by and drive regularily.....this turned out to be a huge problem for me i want to put a flow master on it because it sounds pretty wimpy, and the muffler looks soon to be shot. I found a kit in jegs for almost everything, but the muffler is a force II and im not familiar with the sound it puts off. I definitly know that the american thunder is the way to go . help me out i wanna know ur input on flowmasters mufflers.
