Re: Braking the Ceramic Stuff out of my CAT's...

Regarding this feline surgery: I found in the 90 90 quattro 20v that the car
actually performed better with the cat in tact. Something with the engine
being designed to operate with a certain amount of back pressure. It ran much
smoother and noticeably stronger with the cat than without. 

Any data/expert explanations of this phenomenom?
