IMHO the header cat is the more important one to remove for power gains, so that further downstream cat shouldn't matter too much. Now make it so Nameless, so you can have all my pennies!
As much as I'm averse to buying parts that don't make power, I would buy a resonated midpipe if it functioned well in noise reduction and was lighter than the OEM component.

Well said, I have the exact same position on this. My locality in Virginia also has emissions via OBD with an additional visual inspection.
My only other request is that the cat be within 6" from the second cat's original location (I <B SCCA.)
I also thought it would be nice if we could cram sound & emissions onto the downpipe, thereby leaving everything else straight through until you hit the mufflers. That way for the track you could toss on a straight through downpipe and dump for a lightweight straight through race setup.
