Looks like I finally have to replace my cat. Having browsed the archives I found numerous opinions and comments on Catalytic Converter brands and costs.

Is there a summary thread that I missed? If not, I'd appreciate the latest info from the group on the following:

1) OE or Aftermarket
2) Recommended brand
3) Expected cost of parts & labor

I'm planning to keep this car forever, so I'd prefer to spend a little more to ensure that I get a quiet trouble free cat.

Thanks in advance, everyone.
