Re: strangled CAT symptoms.....
Well, you would have to look for a tell-tale sign as to why it could be choked as it's not easy to diagnose a blocked CAT with it in place...
Does the car smoke on gear-change or when pushed at high rev's? If so, a build-up of oils may be present in the unit and could cause that. More likely you would see loss of willingness to rev high when the most air is going through the system.
Best to remove it and check by eye. You need to look down the side facing the front, you should see the matrix and it should look clear in all ways.
