Is my cat clogged?

My van passed Oregon's smog but I just found out that for that year they hook up the car to the computer - through the computer's harness and not at the tailpipe. If the cat is bad will it suck engine performance? gas mileage?

If the cat is bad, it will definitely cause running issues and bad fuel economy. I would suspect your SES light to come on showing a code though. Mine did on a trailer towing trip. The cat came apart and partially plugged the exhaust and we had a hard time running the van the 200 miles home...towing a trailer!
To check for a bad cat, start the van up and take dead blow hammer or rubber mallet and tap the cat. You are listening for a ringing and for pieces rattling around.
