GM ASA cam vs catalytic converter life expectancy How do cams like this or bigger cams in general effect the OE catalytic converters life provided a proper tune is done and both cats are almost new. I understand it's a crap shoot but are we talking a matter of weeks or years provided the tune is dead nuts and it's not raced just a generally easily driven car.

I dont think power level affects cats as much as a tune would. A pig rich car would clog cats pretty quick...get some hi-flow cats and a good tune, you should be fine.
