I recently discovered issues with my exhaust and due to financial issues im having to fix it on my own... I Straight piped the exhaust and i have a flowmaster super 44 si/do that i need to put on. I noticed after fighting with it for a hour that where i was going to put it, will make it rub on the driveshaft. I can move it up some but id have to remove the section of original pipe that has the back o2 sensor... what im needing help with is figuring out if i need to move the sensor/ remove it/ or what, and how to do it. Ive never messed with this kind of stuff and the local muffler shop is closed due to a death in his family. Any ideas would be appreciated

 

Know this is late, but can't you twist the muffler enough to get it to work? Just a thought.
