Does anyone have a 496 MAG STD riser sitting around that they could get a measurement off of for me, see sketch below. I need to know what the largest diameter of the exhaust tube is at it's end location.

Thank you

Changed the sketch, need 2 diameters.............

Did you get your answer. I have a set, pm me. I'll have to find them. They are in a large pile of parts. Lol

Thank you. No I did not get the info I was looking for. I'll PM you when I get to my computer tomorrow with details as to what I'm looking for, greatly appreciate any help you can provide. If possible, can I borrow one from you to measure out and research. I'll pay shipping round trip.
