Any way to find a low mileage wreck and scavenge parts? If I had to buy aftermarket I'd probably go for Eastern Catalytic given they specialize in such things. Having said that, every aftermarket exhaust part I've dealt with did not fit 100% either the flanges were at the wrong angle or the hangers were off, or something else.

I agree with Lexus2000. If you must than get an OEM one from a scrap yard

dId you verify the Cat converters for functionality?

A working Cat converter will have an output temperature much higher than the input temperature. You can verify it by using an Infra red temperature gun.

Iíve put 89 gas once or twice in my car. Always 87. I figure if 87 is that bad, Lexus would say do not use it under any circumstances.

Scrap yards will almost never sell converters either due to environmental laws or they want to refine the valuable metals from them.

Never knew that.

Luckily I never had to deal with this problem, and hopefully never will have to.

It probably isn't that bad once in awhile, but using it for 150k (which is how many miles the car had when i got it) may do some damage.

I MAY have fixed it. I swapped out the straight foulers for the 90 deg ones that were linked in this thread. I drove 100 miles so far, no light yet. Fingers crossed.

glad to hear that. I was pretty surprised when you said the foulers didnt fix your problem. Im thinking it's because the sensor is still sitting too close to the exhaust where as the one linked is further away
