Anybody put exhaust cutouts on a 300C? I've seen and heard them, but I've never used them. I was looking around for an exaust system, when I ran across some of these from DMH performance. Seems it could be the best of both worlds.......low key factory exhaust one minute, then push button Hemi grumling the next minute. Not to mention the performance gains from an open exhaust. That would be an imposing sound for those pesky ricers. Anything I'm missing here? Anything to be concerned with?
