Question regarding catalytic converters...

[bmwm3n528]

Is the life expectancy affecting by driving style?

Thanks,

Is it affected by driving style? I'm sure everything is affected by driving style, catalytic converters also need to warm up to full operating temperature to be fully effective. So short trips can without letting the car warm up completely can affect the CC as well. I'm sure the more aftermarket sh*t you put on the car would probably affect the life expectancy of the CC, especially forced induction. Although CC's don't crap out too often, if they do it's at a really high mileage and they're easy to come by cause people get rid of theirs all the time. Just my o2 cents...

BMW says to replace them every 80,000. My last emissions on mine passed by one point, and that was with 101,000 miles.

I have a feeling I'll be getting new cats soon.

I didnt pass emissions when i was at 113k on origional cats, i got them replaced with new ones for about $200 and i passed first try. Very simple welding replacement that any muffler shop can do.
