well the 3 bolts connecting the cat to the exaust has seized. hopefully my air tools can break them free. also whats the best way to remove the 2 oxygen sensors. i don't think there is enough room to use a wrench under the car to unscrew them. i will be doing this tomoorow

 

to remove seized stuff use liquid wrench, i used it and a large ratchet and i got them off. as for the O2 sensors...a bigass wrench i htink like 21 mm or something it was huge. just fit it under...

 

Pull the wires (fron the rubber grommet) down, there is more wire inside the car.. then un-clip it fron the connector and the 02 will come down with the CAT.

Remove it easily!

The one from the header can un-clip from the connector a little further up in the engine bay (follow the wires)

 

how far in is the clip in the rubber grommet. i don't want to pull to much.
thanx

 

its not that far.. dont worry.. its tough, tug it out!

I can actually see mine (no interior) its on the floor behind the ash tray!
