Decide where best to mount it and weld a boss into the pipe.
Somewhere similar to stock location would be a good plac to start.
You can get bosses off eBay (M18x1.5 iirc). Get stainless if your manifold is stainless etc. otherwise any decent exhaust place, Longlife etc should sort you out for not many £££s

dont run car without the lambda, it can cause damage and running issues. so you will have to remove the exhaust from the car and have the boss put in as cheys has already said
