Husky Part #?

[Tree Sling'r]

Looking for the part number of a screw on exhaust port. I have been told it is a Husky product. A modified MS660 I have from Idaho has one on the muffler as a third port. I like this screw on style over a screen rather than welding one on. Anyone have a clue of what I am talking about - is it even a Husky part?
Thanks -

I suspect that what you are looking for is in frame "D" in this Husky 288 IPL.
