2nd cats removal

Will it mess up the O2 sensors by removing the 2nd cats? will it be louder? and will it free up some HP? Not interested in making it louder if not going to free up some HP. And would you just cut the cats out and replace it with a piece of pipe. Thanks in advance for your help

2nd Cats Removal

It will not affect your 02 Sensors. The sensor is in the front cats. You will also notice a little deeper tone and slight power increase.
