Default O2 sensor questions

I'm about to put headers and an off road y pipe on my 98 TA w/ 120,000 miles. I have already turned off the egr, air, and rear O2's, but I was wondering if I needed to change my front O2's? Do they wear out, or throw off readings with age? Are there better ones that are more accurate?
Thanks

I would change them if they are the original ones. Just get AC Delco O2s for the front and you might need wire extentions. You can get those at summit or the like
