I have 2.5" on my truck but it is coming out of the turbo. The larger later model manifolds are 2.25" if memory serves me correct. The 2.5" barely fits between the starter/body/e-brake and took some dipstick bending too.

As for muffler, I am using an MBRP 2.5" resonator ( https://www.amazon.com/MBRP-R1012-Overa ... B000OB175M ) that has diesel as an application. It keeps it where I hear more under the hood noises versus out the back. When my exhaust came apart going down the highway the one day I really appreciated how much this resonator quiets this diesel down.

I also have a manifold out of a C240 sitting at home that would bolt up to the C223 block but the exit is straight down versus an angle like the stock NA manifold. I can take a picture if I remember.
