Hi Rich,
Yes these are the closest to factory replacements that we could find. If you need SS pipe after the mufflers you will need to get that custom made from an exhaust shop.
what are the measurerments of muffler, and will this direct fit 2008 workhorse ufo with rear 8.1 engine

Overall length is 28" and body length is 22". We have fit them on UFO chassis's without issue, you will just need to cut the factory pipes as close to the muffler as possible so you can reuse the flanges.
I was wondering if you could tell me what the inlet and outlet size is?

The inlet and outlet size is both 3".
