bad cats
bad cats I am getting my SES light on my 2000 SS and found out that it is two codes for my cats. Does anyone know if this affects my performance any? I dont think the cats would be really plugged at this age in its life but dont really know for sure. Is it common for both to go out whether being plugged or just both sensors to go out? Help please...

Re: bad cats KillerD, I had Bassani y-pipe w/ cats put on my car back in November and now have an SES light due to a poorly functioning 6 month old cat. So its possible that the cats could go so soon. You will lose some performance from a bad cat. I suppose its possible for both cats to go at the same time, however i doubt it. I'd bring it in and have reputable mechanic check it out to see what your problem is exactly. Hope this helps and good luck.
Re: bad cats The codes set because the computer isnt seeing the proper rear O2 activity. Lots of things kill cats, oil, antifreeze, too rich, too lean. Your cats can flow just fine and not work properly. If your exhaust is stock (I dont know what mods you have) it should still be under warranty. I dont have my owners manual handy but I think the cats are warranteed for 7yrs/70,000 miles or something like that, they messed with the emissions warranty in the last few years so look in your warranty booklet to see whats covered..
Re: bad cats Bassani seems to have problems with their cats. My brother got an x-pipe for his Cobra and one of the cats broke after about a month. There were rattling noises inside the cat and it sounded like crap
Re: bad cats No noises coming from the cats but who knows. Thanks guys for the responses. I will definetly take it up to the dealership soon. The exhaust is stock from the manifolds to the cats but from there I have the loudmouth on. But I dont think that would hurt the cats by any means.
Re: bad cats Gut the cats and install O2 Simms. You should see the square wave the O2 Simms output on AutoTap. If you think Bill pulled the wool over Hillarys' eyes you should see the job those O2 Simms do on the PCM.

Re: bad cats PO420 is what im showing too, i just try to ignore it and pretend my cars nice. I only have 23000 miles, but i say screw getting a new cat from the dealership, im going to go with macs w/ory or hooker lt's w/ory. Then i think ill invest in some ls1 edit action. This with efilive 5.0, should be a very nice combo to have at my disposal...
