It has 2. Yes. it would throw a code for cat inefficiency from the rear o2s. It can be tuned out if you want.

Anybody with tuning software (HPTuners, efilive, etc.) could tune them out. Your best bet would be to take them to a shop with the software.

Yea it won't affect driveability at all, you'll just have to live with the SES light on all the time like me. It's been over two years since LTs and an ORY pipe. I'm waiting for the SES bulb to burn out
