Bypass pipes installed! Now a problem?

AndyA6... you have the bypass pipes on an '04 right? The o2 sensors are on the primary cats. Adding the bypass (secondary cat delete) pipes does not effect the operation of the o2 sensors. Go by a cheap, $50 code scanner and see what comes up. I always clear the code and ignore it the first time. If it comes back, then I will see about doing something. Actually, I have cleared a code for an “aging o2 sensor” about 5 times now. I probably should do something about it.
