      My BF's truck was so loud we could barely talk while driving -- not to mention the lovely vibration that I hoped was helping burn calories every time I took a ride with him. This new muffler made such a dramatic difference I always want to ride in his truck and sometimes we just listen to the smooth silence.

      Says it's a direct replacement but it's not the same.size or the same number of inlets and outlets. On top of that it came dented and scraped up during shipping.

      The muffler is a nice replacement for the stock muffler. I did use the Walker tailpipe because there isn't a back hanger attached to the muffler, but is on the tailpipe piece. It leaves the vehicle with a quiet,modest sound.
