I received my dynomax vt muffler #17956 today and installed it. It installed really nicely. Its a 2.5" offset inlet and center outlet. Cut off the old one and installed it in a about 2 hrs. welded in real nice. its nice and quiet at idle and cruising. I did a short run at about 65mph and there was zero drone. truck sounds nice (it gets a bit louder) when i step on the gas. It no way is it obnoxious. I highly recommend it for a after market muffler. I would put up a audio clip, but they are just about worthless to really hear what a nice exhaust sounds like.. I wouldn't think twice about ordering it again. One thing though, lets see how long this valve lasts.
