beat the topic to death~~~
I'd say 90% of the time its the O2 sensor, $500-ish job from a dealer, much cheaper with a friend or DIY. Seems to come and go, but if you live in a state that plugs your car up for annual inspection, then it'll haunt you.
I was told my other sensor is failing soon by the dealer, sigh...
Good luck.

I don't know about the 3 year warranty, mine just expired.
As for the longer 8 year Federal Emissions Warranty, AMLI said it's not covered. (read the book again myself, seems like they're right...)

Seems like O2 sensors are a pretty common failure on the V8, and frankly don't last very long. If it was a product I felt we could source and improve upon we'd look into it but I have my theories about why they fail. I have seen a lot of OE cats with heat rings/discoloration and I have a sneaking suspicion that the O2 sensors are failing because there's too much heat build up in the catalysts...
That's the only picture I have to illustrate, but look at the heat ring around where the Lambda boss is. Just a thought anyway... could be completely wrong.

Again, this is far from being a peer reviewed Scientific study, just me thinking out loud and trying to explain the high failure rates.

I guess it's time to start setting aside some money to move away from the OEM cat. To have the car a bit louder won't hurt either. Maybe I'll put it in when I take the car in for the 30k service.

If you want some 200 cell cats and this is a good plus point for going for them then that's a different story!!!

I just want to make sure I don't come across to badly. Obviously I'm biased so I should state that for the record, and this is just a theory I have. I also think that moving the Lambda bosses away from the matrix which gets the hottest and into the cone should help. But you have to figure out what the priority is, because you could buy 4 or 5 new sensors for the price of a set of cats, and whether replacing them with aftermarket units may or may not be a fix.

Thanks for the info. I know it's more of a scientific assessment, but if you observe that the RSC cats run cooler, then I'm willing to give it a shot. The thought of taking the car in 4 or 5 times to get O2 sensors fixed really bothers me. :P
While I do know quite a bit about cars in their stock form, I know very little about aftermarket parts and performance improvements. What difference will I feel or hear with the RSC cats?
btw, thanks for all the help, starting from late last year when i was looking into the idea of purchasing a Vantage.
