you can put the o2 sensor back in the pipe as long as you screw it into a "spark plug non-fouler" first then screw both into the pipe. that will keep the sensor from reading "bad" exhaust and throwing a code.

i put duals on my truck but what i did was i cut the pipe after the last o2 sensor and put a "muffler" single in and dual out and ran both pipes striaght back. i still have all the cats and sensors. but it sounds great! and runs better.

the reason i didnt put true duals on it is ive heard that you loose too much back pressure and loose power.
