Can find them for others, but not for these.

Thanks

Just out of curiosity, are you asking about a separate plate that fits between the manifold and the riser with an 02 bung? Like a nitrous plate? That's brilliant!! Why wouldn't they have that? I would have opted for that instead of having the 02 bungs installed in the risers. I could have "clocked" them for a better routing of the sensor wiring. It would also be an affordable way to upgrade an older exhaust. I just realized why they wouldn't have that for sale. "Affordable" is not in the vocabulary of anything tied to boats

If it's anything like my Gil exhaust + risers, I wasn't able to find any readily available online. I paid a local shop to weld one in at the 2oclock position, don't have to worry about the extra riser height

SB,

It would appear you're looking for unobtanium.

From what I've seen, these are pretty basic parts that a guy with a little knowhow, some dimensions and the right machinery could make. I happen to know a guy and he's been known to work off of napkin sketches before. Hint, hint....

Thanks. Brad.

Thanks guys. May contact you.

Later last night I found this.

They’ll make one for $160.

Only issue i can think of is their pictured adapters are not angled. I would think they would need to be for exhaust to line back up. Right ?

My eddie marine manifolds/stainless risers are the non water pass thru type.
Uses this gasket:

I think i have some spares that could be used as a template.

SB,

Without knowing the length of your tails, I'm gonna go out on a limb and suggest a 3/4" - 1" thick O2 spacer isn't going to change your angle enough to have to worry about how the bolts will no longer align through the holes of or seat properly in the riser. I would think you'd have SOME flexibility in that assembly. Just guessing, though.

Thanks. Brad.

Talking about lining up tails and hoses to transom/tips.

Is this the connection point "risers to tails" that you are talking about? If it is, then you won't have any problem. Mine are not in alignment plus the exhaust ports on my heads are raised and the 8-1/2" connection hose was no problem at all.
