Does anyone make rams horn manifolds for LS3/L92?

Yes. Speedway sells Tru Ram manifolds for LS engines.

I dont think those are going to fit an LS. The Tru-ram manifolds Speedway sells dont look like ram horn manifolds at all, they look more like a big block manifold or a 5th gen Camaro.

These look very similar to what is stock on early 1960's Corvettes and Impalas. You can see in the image the exhaust port spacing looks like the SBC (Gen I/ II style) which is incorrect for our engines. In the Q&A section it says several times these are for the Gen I / II SBC (350, 305, etc.) engines.

In short, no these will NOT work for any Gen III / IV (LSx) engine.

Too bad, Those would be ideal for tight spaces.

Not a rams horn but the LS3 Corvette manifolds are center dump. I ended up using one on the passenger side of my 55

Not manifolds, but Hooker does offer several options for center dump LS headers.

So does Sanderson. I have a set of Sanderson block hugger style headers on my 1961 Impala.

I used the 1997 Corvette "sheet metal" manifolds that are tucked-in and dump almost center.

SPEEDWAY does have what they call Tru-Ram.
They come polished

I think Vette take-offs is what I'm gonna end up using too.
