I think 1.75" at the exaust manifold, but from the cat back it is 2.25"

its the same width from the headers to the cat and from the cat back... you have to get a custom job to get 2.25 inch catback as I have...

I thought the down pipe is 2.0" the the flex pipe is 1.75" to the muffler.

the OD is 1 5/8", at least from the cat back, if you wanted to know.
