Waste pipe attachment

I'm doing some garage work and need to attach a new sink in a different location to where the last one was.
I have a galvanised steel pipe coming out of the wall at a mad angle. This screws in to the vertical waste pipe. It's a 1.5" pipe.

First off - how do I unscrew the thing! I've tried a strap wrench and can't make it budge. I've soaked it in WD40 overnight to see if that helps...

I want to remove or adapt this pipe so that I can get the sink over to the left side of it. A picture may help (attached).

Looking in HomeDepot I don't see the bits I need to do this.
Do I replace the steel pipe with a PVC male to female insert? And then use PVC to get to my sink? Or is there a better way?

Thanks
Marc

If it were me, I would cut the steel pipe with a reciprocating saw about 2" from the wall. Add a no-hub (shielded) coupling and adapt to PVC, then turn 45 deg and go wherever you need to. Since it's a garage, it's not worth the hassle to make it perfect. If it was a bathroom, some extra work might be worthwhile.

If you are set on getting the pipe out, you can use a propane or MAPP torch on the threaded connection. That will likely soften whatever putty/paste was used when it was assembled. And you may need a larger (18") pipe wrench. The strap pliers are great, but don't get as much torque as you need with larger threaded pipes.
