Doug Thorley Headers with SB Trick Flow Heads

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.
Upper photo is the Stahl set, lower picture is indeed the new set of 5303's I found. Sorry for any confusion.
