If my memory is correct, it is 2 1/2".

Ignore the nasty looking throttle body for now, I have another one ready to coat and rebuild, just haven't got to it yet. I'm debating if I should do it in black chrome like the piping/intake mani or maybe matte black.

I also have another CAS that will look a little better smile
