Default Both fwd O2 sensors?

Both went bad within a week of each other. I took the Z down to the dealer and they diagnosed that both O2 sensors in the front were bad so I'm wondering if that has something to do with my Berk HFCS (they have been on trouble free over a year) or maybe my exhaust, or if I'm just unlucky?

Also should I just let dealer put them on for 700 bucks or DIY for 400 bucks in parts from NAPA!
