They are the extinct Accel/Lingenfelter headers. They are stepped 1 5/8" to 1 3/4" to 1 7/8". They look an awful lot like SLP's old tri-y's but they have a few differences.

I got lucky. They where $750US when new and I got them for roughly half of that. They have never been installed and have been coated at JetHot. They really didn't make very many sets of these.

I did have a set of SLP 1 3/4" mocked up when you visited. They wouldn't clear the plugs on the heads so I had to sell them. I've been running the stock manifolds all summer.

They look great dude. You gotta love it when you can make certain members drool all over themselves, when you get a deal like that. Jethot is the nations leading header-coatings manufacturer. I read an article on them in Car Craft about 2-3 months ago, about the same time 16 Owner was buying his. They not only do the outside, but thet also coat the inside for maximum flow and longevity(life).
Good score!

Thanks guys, I like them too. I got them through the classified ads here on thirdgen. The gentleman I bought them from is selling all his accumulated goodies to buy a FireHawk, #23 I think. He also is selling/has sold his '91 Formula that may have been the nicest car on thirdgen. He's a great guy.
I have that Car Craft article. I was amazed at the temp reductions between the coated and non coated headers. The power gains where minimal but they said you could put your hand on the coated header 2 minutes after shutting the engine down.

At least the air tubes don't extend down into the header tube itself. The air tubes on my Hedmans were about twice as thick as those and stuck into the dam tube for about 3/4 of an inch blocking a good bit of flow.
