Scat tubing size going from fresh air on top of engine into muffler?

[jM20]

Hi,

I don't know if this tubing is 2, 2 1/8 or 2 1/4?
This is a M20C. The orange hose hanging out the bottom that is 3' long.

Regards,
Jim

On my ‘63C, that duct is 2” diameter.

Why not just measure the ID of the old hose or the OD of the male input on the muffler?

2” on my J as well.
