1989 Chevy 5.7 need new catalytic to pass CA smog

Yes, forgot to mention new O2 sensor as well. It passed with flying colors, emissions as low as a new car according to the tester guy. Quite an amazing improvement, all the levels were super low. A testament to how well emissions equipment actually works...when it's new.

Glad to hear you got it to pass and it sounds like it should be running great now. These trucks can go a really long ways and I am sure you will get many more miles out of it. Mine has 293K and still runs fine.
