I have a brand new set to go on my Duster. Going to dyno engine with both these, and the Stahl headers it currently has.

You sure that's a Stahl header in the bottom picture? I'm betting that's a Hooker 5303 header. I have to walk out and look at my header to say for 100% sure.

Also, I've found power with that Hooker header and a 3.5 inch collector.
