Tailpipe

[jdross440]

What is the diameter of the stock tailpipe where it comes out of the muffler? I did a dpf deleted several years ago on my 2007.5 (6.7 Cummins). I don't remember is I changed the tailpipe and muffler or just added the delete pipe forward of the muffler and can't find a receipt except for forward pipe. The tailpipe on now is 4" where it comes out of the muffler. I was rear-ended this morning and the tailpipe end was crushed.

So it is, starting with the 04.5 MY, before it was 3.5".

03 -04.5 is 4” turbo outlet, elbow necks down to 3.5, stays 3.5 to muffler outlet, and tailpipe opens back up to 4” just after the flange from the muffler.

weird design.

AND found out the hardway that most stock replacement tailpipes dont open back up to 4”, so I wasnt able to reuse my tip.
