2001 sentra 1.8 throwing p0430 code

[g50president]

So when i bought my car i had the check engine light on. There was no exhaust just nothing after the cat so it was loud. i recently redid all the piping back to stock pretty much and deleted the P0430 code which was cat something bank 2. the lights still off as of today after i deleted the code. im just wondering if my cats failing? any word?

Check your O2 sensors, that's usually the issue when that code pops up. Cat is also a possibility, though.
