Catalytic converter direction?

Hi, I've been working on installing a header on my '90 240SX. In the process I had to drill out the rusted bolts on the cat and get the holes rethreaded. Now I can't seem to figure out which way the cat goes back on. Attached is an image of the cat. Could someone tell me which end is which? Thanks, I've searched through hundreds of pictures and many threads and haven't found my answer yet.

Catalytic converters work both ways.

However, there is an EX on one side which I believe is EXit, so face that towards the catback.

It's upside down but facing the right way.

Or you could quit being a cheapass and buy a test pipe/high-flow cat:-D
