What are the symptoms of a dead catayst. I am losing power at the top end and there is a smell of burning . There is also a rattly noise at about 5000 revs.
Dead Catalyst Symptons

Not so much a dead cat, more of one that is beginning to break up and block the exhaust. Initial symptoms will be loss of power at wide throttle openings, and a very hot exhaust system pre cat.
Drop the cat off at the downpipe and peer into it. You can remove the O2 sensor if convienient, and go for a quick road test, but invariably they are seized and a nightmare.

I will investigate next weekend.
The ceramic honeycomb affair inside the Cat had rotated and the exhaust gases were being restricted.
Put a new Cat on and performance is back to normal.
Thanks for the advice.
