Removing the CAT System.Hello all, I have a 1999 RX300 with 177,700 on it. I have a blown out flex pipe (I really hate this component) and upon inspection I pulled a half dollar size piece of debris from the third (by the muffler) cat indicating that one (or both) of the upper cats have collapsed. Could I remove all 3 cats and be fine like I have done to several vehicles, or would if make the motor run worse? And what about the O2 sensors, would I remove them or custom fit them to the catless system? I have not messed with imports before but I have always done my own mechanical work and also do classic restorations.

Thanks in advance

Scott
