Stainless XS Supercomp headers!
The works manship on these headers is second to none they are perfect as far as welds and fab work goes. It will take me a little while to get them installed as I am waiting on a true dual exhaust and I still need O2 extenstions and sims plus these headers come with no hardware or gaskets. Iwill probably reuse the stock bolts if possible and go to GM and get a new set of Stainless gaskets.

Let us know how they fit when you get yer duals, bub.

Did the true duals bolt right up?
Damn good deal for $300. It sorta tell ya the markup on them.

Anyway you can tell if the flanges are stainless too? I read on another forum that ssautochrome headers dont have stainless flanges, but then again I'm not even sure how people know these are from ss autochrome.
I did some research and they use 321 stainless compared to Kooks and QTP with 304 stainless.
321 has Titanium added to the composition and a greater heat range up to 900 Cel. I know exhaust doesnt get up there but it is used to fabricate jet engine exhaust manifolds according to some articles.

321 should be less magnetic than 304, right? If someone had a pair of kooks or qtps and a pair of these they might be able to tell if they truly are a higher grade of stainless by using a magnet.

I can understand that QTP's are more because of the velocity spike, HFMC, polishing, and simply the name. But I really want someone to get these on a car.











Good price..not good if they hang low like slp though....they look good..5/16 flange you say.??..hope they go in easy for you...
