Thanks Eric Can you advice me on if it would affect my performance? I went to one exhaust place and they said that removal of the CAT could reduce my performance and the car might not run right?
Someone else said that it might sound like a toilet
Do you know of anyone who has a de-cat pipe on a 2002 9-3 Aero?

Exhaust places, who'd have em, a Cat is an obstruction which slows the air exiting the engine, remove obstruction and you increase performance. The Cat is there to remove pollution and in tandem there is a lamba sensor which monitors the level of O2 in your exhaust gases and gives the info to your ECU to adjust the fuel metering so as not to sent too much inburnt fuel to the Cat which destroys it, when you remove the Cat you should keep the lamba sensor to maintain the signal to the ECU and maintain your emissions and fuel economy. As the lamba sensor only has a small window of detedtion you should get your car emission checked and adjusted after the Cat is removed to make sure the emissions are within the window the lamba sensor can detect.
