Cat?
I'm assuming you're talking about the pre-cat...
It's bolted on. You have two options:
1) Find a replacement at a junkyard
2) Buy a downpipe
I'd go with option two. The pre-cat is just there for cold start emissions, and they OFTEN clog up, making them a hazard to your rotary's health. You'll still pass the sniffer with it gone. A downpipe will help you see a little bit more PSI on your boost gauge too.
If you were talking about the main cat, it's bolted on too, behind the precat.
