Remeber the dutweiler thunderbird that ran comp eliminator. It ran a 399 ford, and said it had 1.5 inch headers, they looked like 1 5/8's to me but may have been pretty thick. It only ran 6.70's about 10 years ago..... it probably made in the 1600 hp area I bet.

i used 1 3/4" stainless for my header material, and then a stainless works collector and 2 1/2" stainless for my crossover from the merge to the turbo, and from the turbo all the way to the back of the car is 4" stainless downpipe. and all my cold stuff is in aluminum 3 1/2" and 4"

If you could link up a pic for me to view, that would be awesome. I'm not really sure what you mean by the term "crossover" either. I was thinking more along the lines of something like the pic that I have attached. But I am unsure of primary tube sizes for the application that I plan on running.
but just like your pictures show...the headers are all 1 3/4". the "Crossover" is in 2 1/2" the crossover is the piece that goes from each collector/header to the turbo.

Will the mild steel hold up in a 20psi of boost situation for a street-driven car?
I appreciate all of your input, fellas!

Thing to remember is that the more area you have the less velocity you will achieve unless you are going to spin it hard. Gotta have velocity to get the exhaust wheel moving. Just part of the puzzle.

Volume > velocity.
Although you need the velocity, the volume of exhaust is more critical. So you need to find the size that maximizes velocity without impacting volume.

I am not sure on the truck manifold size, but I just put on a pair of C6 manifolds and they look A LOT better than the stock 2001 F-body manifolds I have.
The other nice thing about the stock manifolds is that they are cast and durable. I have twin TC66's from Forced inductions and they are capable of 1000 at the tire.
So I decided to run the C6 manifolds for cost and ease of installation. Plus they are durable and they are easy to change plugs on.
