Do you not have the correct size wrench? Is it stuck?

It unclips behind the motor near the black crossmember under there. Penetrating oil should help you unscrew it, Mine was not that tight.

Hey.. not sure where you ordered the DP from, but if it was Clear Image, they are always very helpful.. just give them a call and they could probably walk you through it.. GL

Do you have a O2 sensor socket? They really help in taking them off.

A judicious application of propane and a spark works well.. (aka heat around the o2 sensor with a torch, it will come right out)

Oh yea, make sure you re-apply anti-seize before putting it back in. Anything that screws into an exhaust should have anti-seize on the threads.

Thats how it goes when you actually are trying to make things so that they are servicable. All the heat and moisture in an exhaust will rust everything eventually, anti-seize will make it to its more of a breaker bar job, not a torch/breaker bar/hammer job.
