Ok, I'm going back to work in a few weeks after I graduate and will be able to start looking at Jeep mods again. The first thing I am looking at getting is a new muffler. I want the added power, sound, and fuel economy for the Jeep. However, I'm doing some research and what dimensions do I need for the Jeep? I don't want to lose ground clearance from it. Also, which provides a deeper, throatier, not ricey sound? The Flowmaster or the Magnaflow?
