I've been saying this over and over, just put a test pipe in the mid pipes with a couple of cats in there. You could probably just reuse your stock cats from your stock midpipes with a bit of cutting and welding of flanges onto the stock cats. One of the cats is mishshaped on the opening but I bet it can be done. It doesn't have to look pretty, just for when you go smog. Then take it back out and replace it with your straight/test pipe.
