Muffler Leak?

[royalkangaroo]

I noticed the other morning when I came out to my truck that there seemed to be a small stream of exhaust steam coming from bottom seam of the muffler. I took a video the next day, but unfortunately it's hard to see. Is this cause for concern?

When I got my truck - I looked under it and noticed the exact same thing. I called the dealer and they said its by design.

Its got something to do with allowing any condensation (that may build) to escape.

Yep, both my 2014 and 2015 had this. It is normal.

It is a drain.

mine does it too. drain the condensation

If that drain isn't there, the muffler will fill with water from the condensation. If oriented the right way, it can freeze and split...
