I put a test pipe in and now I have a rear o2 sensor code. Is this because of the straight pipe adding more flow in the exhaust throwing off the o2 sensor. Or do you think its simply because the o2 sensor is old(100,000 miles). Anybody with a straight pipe have the same results? Any info is greatly appreciated.

Thanks,

eh...I had 50k when my Rear o2 sensor went out. This was before I put my test pipe on. No problems since replacing the o2 sensor.

 

my test has caused no 02 problems
