We all know they are 1.75" primaries, and fairly long.
Most people run the 3" ORY with them.
Another thing I found is that Stainless Works makes a LT with 1.75" primaries, decent length, and choke them down to 2.5" at the collector. I dont understand this 2.5" collector idea.
I know this thread is about an 8.1. I am only hoping to pull out some more "general" header info.

There's no such thing as "choking" it with a 2.5" collector / Y-pipe. Dual 2.5" pipes flow sufficiently to support over 500hp. So, unless you're making some serious HP, 3" collector/Y is overkill - and actually can reduce your exhaust velocity....

The collector on the SW doesn't look like a very smooth transition. I won't argue that 2.5" is large enough for 1 bank, but even the stock Y is 2.75 (smashed)
SW is the only Co that I have seen with the 2.5 y setup. Was it done purely for performance? less $ for tubing?
