Exhaust Size

[Kurly154]

I have a 2001 Expedition with the 4.6L. I was wondering what size the stock exhaust pipe size is? Thanks.

If I'm not mistaking, I think my 4.6 has a 2.5" piping.

it may be 2.75 with ford's wisdom going on an odball size....

Thanks for the replies. I have a hole in first muffler and was wondering what the size is so I can buy a new muffler.
