: What size is the stock exhaust pipe piping for the 6.0?

I'm thinking about swapping in an aftermarket muffler instead of going the full catback route. Not sure which muffler to order though.

Ive been looking at exhausts too. From what i've read, i believe the stock piping is 2.75", but am not 100% positive. What muffler options are you looking into?
