My 05 is 4 inch all the way back. Stock muffler is a "S" design which is quiet but restricts flow. I went with a MagnaFlo 4 inch setup with band clamps for now.
Seems to be a quality setuo. Might weld it up someday when I'm done messing with it. I'm running a Hushpower performance muffler and it had terrible drone until I put an FTE resonator in front of it. If your truck is a short box, you'll need to make sure a 51 inch muffler will fit. Donaldson/Nelson mufflers come in multiple sizes and are supposed to be pretty quiet for a flow though muffler. They also cost way less than the muffler I bought.
