What is factory exhaust size on 6.6 gas trucks?

Looking for the OD of the exhaust on the 6.6 gas engine.

It’s 3.5” exhaust so if you’re ordering exhaust parts that’s the size you order it for.

Yep, I confirm it's 3.5" exhaust too. Just picked my truck up a week ago. Had to order an stainless steel exhaust tip for it.
