how do you get to the passenger side before cat o2 sensor. i can get a socket on it but no room to turn? any techniques? thanks

 

i just did mine, depending on how tight or rusted it is get a 6in crescent wrench on it from the bottom, only if its not to bad mine was so i had to go to option 2, what i ended up doing is cutting the wire and use like a 1 1/2 ft extension with a universal and a impact and went threw the top worked like a charm, oh also use penatrating oil

 

i tried those and dont have enough room. the impact wont get it loose. ill have to remove the y-pipe. any tips on how to do this?
