Default Cat o2 sensor delete

I have a 1999 civic ex, d16y8, I recently got a (pretty much cat delete) hollowed out cat, my dad is a machanic, and said if I put it on it would (f**k up my car) mess up the engine. I would like to know how I would end up bypassing the o2 sensor on the cat. I have taken off my muffler, and looking at getting a new exhaust in the next few weeks. Please let me know how to bypass the o2 sensor on the cat on my 99 civic ex. Thanks in advance.
