No experience with Buicks, but are the stock headers stainless on the jeeps? We have a 91 and no issues, but have seen a bunch cracked in the junkyards. Also our Firebolt has stainless exhaust and no issues with those cracking either. Granted that is an aircooled V twin.

I work as a welder with stainless a lot. Stainless will move more than carbon steel when it is heated. That is why headers crack. Also if stainless is continually heated 1500 - 1700 degrees the nickle is burned out of the metal. You now have basically carbon steel. This is one of the issues with welding stainless to keep it cool so you don't loose the nickle. Here is a very nice header I am thinking of making one similar to this.header
Also take a look at the holes on the flanges on the header in the ebay add not good.

I think a cast stainless manifold with .250 tho walls would do the job better. long stainless header toobs would let the heat of the ex cool to much and you will lose the power of heat. you might gain in flow but in the turbo gas world if you put on headers with the toobs to big you get a very very laggy ride . has any one done back to back test on a truck with a header a manifold? maybe even someone who is not trying to sell one ???

My dislike with the ATS & HTT manifolds (and the stocker) is the VERY sharp turn exhaust gasses have to take out of ports 1 and 6. Plus with the HTT and ATS the large internal gap caused by the assembled sections. Most of the headers I've seen have nice gradual bends out of most exhaust ports, not restrictive tight-radius curves, and of course no midstream gaps.

Here is a photo of Industrial Injection's tubular manifold. They basically have them built to order by their fabricator, they are rather spendy but I like the clean simple look.

Just found Timo's homepage, wow his albums are worth checking out. His header is in a lot of the "Older Updates" albums: http://www.devilscastle.net/ (scroll down to the bottom past all the crank machining pictures).
This guy has amazing talent, wish I had 1/10th his ability. Sorry if I'm starting to threadjack. . .

Tubular headers are pretty popular over in the import racing scene. The problem is that when you hang a turbo on them they inevitably crack. Its not just cheap/poorly made ones, I've seen some of the top of the line ones end up with cracking issues. On a race vehicle that only sees 1/4 mile at a time its probably fine but for something that's driven on the street I wouldn't use one. I'd go with one of the aftermarket cast manifolds. Ideally someone would build a cast one that follows routing of the one that Timo made. There are several companies that are casting their own for the import cars now, I don't see why someone can't cast one like Timo's for these trucks. We all know that BD makes one that pretty much follows the stock routing, I'd like to see one that provides a longer exhaust port.
