I recently replaced my catalytic converter with a Bosal direct fit and also replaced my O2 sensor (Mustand 5.0 trick). About a week after the replacement I started getting the rotten egg smell of a catalytic converter on it's way out. Is there something else I should've replaced? The reason I replaced my existing cat was for the state inspection (TX). I didn't really want to put my old pipes back on cause it was such a PITA installing the new cat! Other than that, my car usually runs kinda rich. I'm pretty sure this can cause a cat to go bad really quick. What else can I do? It's kinda embarrasing to have such a stanky car.

Kinda nice increase in torque when the new cat was installed. But I really miss the high end rush when I had the hogged out cat.
