Mercruiser Exhaust Pipe Identification

[20pilot]

Coming off my Manifold/Riser I have a down pipe. I replaced the manifolds and risers about a year ago, but not these pipes because I could not locate them. Of course, one of them developed a pin hole so I would like to replace both. Its on a Mercruiser 350 Fuel Injected. Attached are a couple pictures to help identify the part.

Thanks in advance.

Appears to be an inboard, have a serial number (best) or the year?

Unfortunately, I purchased the boat used and have been unable to find a serial. You are correct this is a inboard engine on a Fish Nautique. If I had to guess the year I would say late 90's.

Looked thru all the 90's years I could find and all use the 807611T exhaust pipe (item 20)

Price is up there, I would google it, found one at amazon for 332

I believe some 3 inch wet exaust and some copper or fiberglass 90 degree elbows should work.
looks to be a double 90 and they are aluminum, heli-arc??????
