wd40 leave for 10 minutes
22mm spanner IIRC hit the end of the spanner with a hammer hard.
You'll be fine without it. If the emissions light comes on, just get a code reader for around £20 and turn the light off yourself.
also i noticed when i took off the cat that there was no gasget there between the cat and manifold, i made my own with a giant dollop of black high temp silicon to put me on till i get my cat fitting kit from nw performance. its not blowing so seems ok for now.
just fitting my decat pipe and got it on ok. however im finding it impossible to remove the old lambda sensor from the cat.
will the car run if i just dont plug it in?
my decat pipe doesnt have a lambda hole anyway so was planning on tying it up.
there should be a large metal ring...

...it was probably still on the manifold, do you remember it being on there?
no silicon should be put on that joint.
