Never heard of the company but there were a lot of short lived hot rod parts outfits back in the 50's and early 60's.
Way ahead of their time as they were welded/flanged to the stock exhaust. Tubbing exhaust manifolds started being used in the mid 80’s on FWD cars to improve mileage and performance. Imports have used them too with much success over hundreds of thousand miles. I didn’t live to far from Norwalk growing up and don’t remember these.
They look about the same basic design idea that were on my 51 Merc when I bought it in 1963 and those were old then. They connected to the stock exhaust and had no flanges. One side had the remnants of a sneaker plug or lakes pipe pipe welded to the exhaust right behind the connection though.
Yes, saw a pair of them more than sixty years ago. IIRC, Fenton and Hedman also offered welded tube headers for the '51-'54 232" Studebaker V8. They all rusted out, length of time depending upon how the car was driven and relative humidity. FWIW, I've never seen aftermarket tube headers for the '55-'64 V8s. jack vines
