Are these rare Doug Thorley long tubes? Please identify these headers.
I'm considering buying these headers for my 85 Corvette, but now I'm not sure on fitment. The seller says they are made by Thorley.
I've never seen anything like them. The Ypipe has a 4-bolt flange and looks like it'd bolt right up to my 85 Corvette cat. The part that threw me off was the upward pointing air fitting. Corvette air fittings point forward. Also, the unusual #2 primary looks like it might stick out too far and interfere with my a/c lines and cat air tube.
Have you guys seen these? Is it possible he's mistaken and these are a Camaro header? I searched but all I found was a post referring to Thorley once making a Fbody long tube, no pics.
Sorry I don't have pics of the drivers side header. He's asking $550 for the whole setup, which I think is worthwhile, IF it fits.

I don't know, but the dent in the passenger-side rear primary looks horrible.
Personally, I'd get something that's tried and true, and without dents lol.

Looks like a dent that is there for fitment? None the less, they still look sweet.. But so do coated Hooker long tubes.

Those are for a corvette....you can tell by the direct down motion of the primaries and the shape of the y pipe. Somewhere on those headers there will be a part #. Look for it and go to summit or jegs and see if the # comes up. Kind of look like TPIS headers.

I would assume it would hamper flow. though I admit I have seen something like that before but always assumed it was bad routing due to engineer not thinking as well. but then I donno

Five7Kid is right, the "dents" for clearance would have zero effect on power. I have seen thrashed, dented, patched, beat up headers used on the dyno make identical power to a fresh set out of the box. Thats why we use dynos, because what you THINK will work better, often times does not.

FYI Five7Kid was being sarcastic as evident in his second post of this thread.

That "DENT" is there so that you can install that Factory GM starter, you know the one that weighs like 30 lbs. It will NOT affect power to any large extent.
I don't know of anything else GM that uses that style of Y-Pipe. I am thinking they are for a C3 Vette.
