Catalytic Converters for CA '91 ZR-1

[Z51JEFF]

What were the readings on the smog? I'm in Ca,mine failed twice because of an over paranoid smog tech. I've got a few suggestions,send me a PM if you like,there are options if you absolutely can't find the cat.

Thanks for replying. All numbers were "elevated" but within limits except the nitrous oxide. It was about 100 over in multiple tests. The car had been driven and everything had been worked on or replaced except the cat's. I got some used cat's but the mechanic with the shop next to the smog shop saw the ZR-1 and was really excited about getting to work on it. He did his "magic" - nothing I hadn't done or checked out already as far as I can tell - and got it to pass - just - without putting on the cat's. He thought putting on the cat's was a BIG job.

I'm holding on to the cat's for the next smog
