I need a quiet catalytic converter.
I just got a Code 67 on my 1996 LS. I'm assuming I should replace my O2 sensors and my catalytic converter since they're 13 years and 203,000 miles old. If anyone thinks there might be other problems please let me know, I'm going off of searches I've made to these forums about code 67.
My question(if I'm right to think it's time to replace these items) is what kind of cat should I get? I should state here that I no longer race and I am much more interested in making this car legal and quite than I am in making it fast. That being said I wont turn down free horsepower if it comes in the form of a street legal and quiet hi-flow cat. Any suggestions? I've been looking at the Magnaflow since I trust the name but has anyone had any experience with these?

magnaflow cats are decent, but its no guarantee they'll pass smog.

There are no CARB legal OBD-II compliant high-flow catalytic converters.
We've covered it in the Integra FAQ.
Check it out for yourself.

Buy an OEM equivalent cat since it is the safest bet for dealing with our smog gestapo.
As far as sound control is concerned, all OEM equivalent cats are going to be a block-matrix type. They will be equally effective in breaking up sound waves, but that isn't their primary job.
If you are on the borderline of breaking Cali's 98 dB(A) sound limit, that's a matter best left to a new resonator or muffler.
