Greetings all A belching, droning noise is coming out from under the car when it is running, a sound whose pitch is directly related to engine RPM. It seems to be coming from a pod-like part of the exhaust system but when I run my hand over all around this pod, I don't feel any air leaks from the tube whatsoever. According to the dealership, my catalytic converter is failing. In the year 2000, Volvo equipped their cars with a CC that is a porcelain screen coated with platinum. The porcelain breaks apart and lets more exhaust vibration occur. For only $1150 I can get a new catalytic converter from Volvo! If I don't do anything, more hydrocarbons will get past the converter and set off the rear O2 sensor and change the air/fuel mix.

The Great Volvo graveyard in Sacramento, California doesn't have any of these things. Am I condemned to pay $1150 just for the part to the dealership? This raises my disgust level with Volvo. Can I cut the thing out with a welding torch and say tough luck O2 sensor ....you're going to be ignored now?
