I have a 96 mustang gt. i have removed 3 out of the 4 bolts to put my new pipes on. but the bottom passenger side bolt is blocked by this weird canister looking thing on the transmission. how am i supposed to get this last bolt off?

 

to answer my own question. and to give advice to anyone who does install these. the easiest way to get the bottom passenger side bolt off that connects your pipes to your headers is to break off the o2 sensor(**** it buy a new one) and go buy a wobble socket. cost 5 dollars at oreilly got the bolt off in 2 minutes.
