I am only getting the 430 code, no pending codes. The cat is a flow master brand.

Did you replace the front or rear O2's? You can have a working cat and still throw the code. The rear O2's just look for a difference between before and after the cat. If the difference isn't what the computer thinks it should be, it'll throw a code. So there's a chance your cat is good, just not good enough. A trick I heard of is to use the spark plug anti-foulers on the rear O2's. They're only a few bucks IIRC.

I had the cat changed out for the 3rd time, so far no light after 200 miles. Took flow master cat off, change to manga flow cat.
