I've had the 16633 installed for a bit and in the past couple days began to look like it was no longer centered. It was also beginning to rattle against something. So today was a cool but good day to get under the car and take a look. It's centered and all buttoned up even better this time. About the sound, it is how the car should've sounded. Yes, there was originally a bit of a drone, but it mellows out a lot after a while. The Crossfire in stock form turns a few heads, but after installing the Magnaflow you notice a lot more broken necks. I've attached a pic and video. The video did not capture the true sound, but gives an idea. Later this week I will pull out the mic/equipment with the laptop and grab a much better recording.
And yes, there are dents in the bumper from when I was rear-ended a couple weeks ago. Chrysler had to order the bumper and it will be painted and replaced in a week.
