i have seen some videos of the 4.0L with a flowmaster cat back and i think it sounds amazing, but i haven't been able to find one for the grand cherokee. Does anyone know of where to find one, or would i have to piece it together myself? also on summits website the dynomax super turbo cat back is pretty cheap. anyone have it, is it a waste of money for just over 100 bucks?
