Default Mac o/r h-pipe

Well I finally got the bottom bolt on the passenger side off, but I'm not sure since this is my first time dealing with this, the o2 sensor on the passenger side up to the manifold went back in correctly with the new h pipe, but the one on the driver side to the manifold wont reach the h pipe, the cord is to short. But I put the o2 sensors back into the holes by the middle of the exhaust. Where are the mil eliminators supposed to go? I figured they replaced the old ones under the middle of the car, but I just used the stock ones. Anyways, besides that problem I only have the bolts from the catback to the h pipe hand tight and the catback is lower than normal and like 2 inches from scraping, and its really pissing me off. The leak from the o2 sensor is loud and obnoxious so I cant really here a difference with the new h pipe. What am I supposed to do?

unplug the 02 sensor and screw it in. then plug the mil in between the o2 and the wiring for it. then tighten the cat back up and see if ti raises up if not then make it sit where it should then tighten it up.

the mils are for the o2s after where the cats would be. you might have to buy 02 extensions for the front ones if yours are too short...but i dont see why they are. i didnt have any problems with mine except i forgot the stupid gasket they sent and have a small leak.
