Need Advise on Cats

Thanks

John,

I won't have anything to compare them to other than the install. I'm going to slip them over the headers and use clamps initially as recommended by Jeff and others with hope of no leaks. I'm sure there is a benefit of getting the high quality RTs as I have used on all my other cars, but I thought I would give these a whirl since I can't imagine feeling or seeing the difference. They look high quality on the outside, but I don't know the technical differences on the inside. I decided to do all my mods at once so therefore the delay.

I believe that too. In fact, it's the first sentence in the first time you quoted me.

What I doubt is that they both flow better, and catalyze better. Otherwise OEMs would use them.

As to your PROM, there is a good chance it would have killed any catalytic convertor. If it was rich, and the cat had air, it will turn all that extra fuel the PROM was dumping into heat. That heat will superheat the catalytic convertor until it eventually is destroyed. Running rich will kill just about any cat, and could be a pretty big fire hazard too.

I helped Demps install new headers on his blue car and we used a bit of anti-seize. he mentioned it helped seal things up. Keep it away from the O2 sensors or anything that might allow it to get on them. We used a real light coating on the gaskets. I guess it could burn off and mees the sensors up. Once again, looking forward to your post(s) on how they work.
