universal Catalytic Converter? on 1997 Audi A4
Universal cats are not allowed here in California, check your local laws. Original equipment cats are always superior construction and last longer than universal cats but cost an arm and a leg. With the engine off get under the car and hit the cat converter with your hand (obviously not when its hot)see if it rattles. What ever caused the cat to fail make sure it is corrected or the new cat will not live long.
