Hello, I bought a 2000 Civic HX that has an aftermarket header installed without a cat and it throws a code for secondary O2 sensor. Best mpg I can get is 33-36mpg all highway.

What kind of catalytic converter should I get for the HX? I have been searching online for over a week and haven't found enough people who have actually changed their factory cat in an HX.

I am leaning toward just a cheap one but I want to make sure this car will lean burn properly with it.
Is this enough? Exhaust Manifold w Catalytic Converter Federal for Honda Civic Del Sol 1 6L | eBay
or do I need to get a better quality?
