Searched the part numbers and found this:
https://www.vintagepartsclub.com/196...classic-repro/ Is this the same as RARE, or some other manufacturer, and what is the comparative quality?

There are 3 different company's that have reproduced Pontiac RA exhaust manifolds.
-R.A.R.E -Classic Reproductions (believe in early 90's was Classics of Ohio(?) -PYPES Douglas, the pics you put up, as well as the eBay listing ChrisP put up are for the Classic Reproduction version. Cosmetically, they look like '69 RAIV GTO exhaust manifolds with the raised part number curving down the outside. In the 90's, I bought several pair of Classics brand '68+ Dport A-body RA manifolds for customers cars, & they held up well. Had no oroblem with outlets/bolt holes being drilled off center Today, have RARE's 2.5 outlet roundport manifolds for my '72 T/A. Other keeper cars, have very clean original RA manifolds. Original 70 RA4/71-72 455HO ex manifolds are easy to spot compared to the reproductions.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
