Sounds awesome! Looking to put a new muffler in my '05 WK 5.7 for some added ear candy but I'm not sure what I want exactly. I love the sound of muscle cars and the loudness doesn't terribly bother me, but that flowmaster 10 sounded a bit too loud... maybe should I go with the flowmaster 40? Also I have a Mopar CAI and a Magnaflow cat-back exhaust system, soooo performance loss when switching mufflers isn't really an interest of mine. Any advice?
