I wonder the same thing. I just got a CEL for a bad catalyst - low bank 1. And I've never gotten these random headaches, which appear when exhaust enters my car. So my guess would be yes. Especially if you notice random test from under car at random times, but no over heating. Could just be a leak somewhere in your exhaust system.
What else can I help you with?
