Just bought a 2012 Ram 1500 crew cab with the 5.7 Hemi and was wondering which muffler would be best to put on. I was thinking about the flowmaster 50 series SUV but didn't know how loud it would be at highway (65-85mph) speeds. Not looking for anything to loud. Just that nice low blup when idling, turn a few heads when you put the pedal down, but still have a very quite cab at highway speeds. Thanks
