Cars made before the OBD port became common were required to have the dynamometer test. That involved driving it on a treadmill-like emissions test machine at the equivalent of highway speed and inserting a sniffer probe in the tailpipe. (The guy was just being picayune about the tailpipe, but they can do that.) The emissions test for later model vehicles that have OBD is still enforced. But they scrapped the dyno test; and I was very happy to hear that because it was becoming increasingly more difficult to find an inspection station that had a dyno machine that was functional.

If I'm gonna try to do the repair myself how do I attach the pipe to the triangular shaped hole on the catalytic converter? Or does it have to be a pipe made for this specific car? I guess thats kind of an off topic question for this site, but since you've been through this I might as well ask.

Yes, when you go to the auto parts store they will know what parts you will need based upon your model of the car. The triangular ended pipe is a flange mount - if a kit is required they can supply it.
