Was it towards the rear 1/4 of the cat? There's two places u can put the lamba sensor on the 92-93 cats 1 at the front n 1 at the back. Same thug happened to mine. Just get some1 to weld the hole up for ya. U find that the crap noise will go, there b more power n ur fuel economy will b much better!!

+1 especially if the hole is perfectly round and has threads on the inside of it. Either weld it up or try and find a plug that will fit it. Some garages carry these as ive used sump plugs in the past with the same thread on them.

Sump plug will or should fit, check you have a lambda sensor fitted 1st.

We had this on a cabby at work. Hole, deffo not for the lambda on the cat, no threads and causing a noise. Really strange.  :undecided:

drill and tap it out then stick a bolt in there if you haven't got access to a welding plant.
