Been offered /6 Stainless exchangers, Never seen the style before Options

[Mark Henry]

Unfortunately I don't have a pic, they don't look like a true header, 3 into 1, very short run (primary) to the big tube (secondary), small box but not as small as the Patrick unit. Heavy flanges but the pipe sticks out pass the flange and would need to be trimmed. Primarys I'd say are 1-5/8", they were over 1-1/2" ID.
They do "look" pro built, good welds.

I was told they were Patrick but they are not these:

They are not H&S

Please, post pic's of other after market stainless units, then the question is what are they worth and do they provide much heat?

Thanks

Those heat exchangers are from a company that used to be in the Phoenix area, GHL Exhaust. Not sure if they're still there or moved to somewhere else. Their website now says that they make systems only for Chevrolet, Mazda, and VW, so I assume they've dropped the 914/6 parts. The main problem with them was that they aren't equal length like all the other headers/heat exchangers I've ever seen. The construction quality was very good, but you can tell from the photo that they do have welds inside the heater shrouding. Also, they lacked access tubes to let you get to the exhaust flange nuts without hassle.
