They look like B&B's without the heater boxes, but they all look pretty similar without the boxes.

anything that cheap would crack, also I would only used 321 stainless on the headers the 304ss works for mufflers not 1400 deg headers

Since I already had B&B headers, I haven't worried about header diameter. If I was worried about it I would check Graham Bell's Forced Induction book (I highly recommend all his books), Corky Bell's book, and do some searching on the Old Forum on the www.turbo911.com site in the air cooled section. If you're going to build your own you could go to www.burnsstainless.com, have them calculate it, and then double check their answer with some other 930 specialists. The turbo has different requirements than a NA car. You don't need to worry about equal lengths and all that, you mainly want to get a maximum of the exhaust pressure and heat to the turbo.

Those are Schnell headers. They were only $799 2 months ago.
