Why do you have to change it? We usually open up them and empty them and put the covers back...

Please elaborate what the cat company people said. Did they say that removing the cat or hollowing it out would not trigger a check engine (CEL) or other warning lights? I removed the black plastic cover under the engine to look and could not see any sensor after the cat so presumably this is the case. If true, the 2006 model is the best because we can easily modify the car without those pesky CELs.

What was the original issue that caused you to think it was the CAT. ? Noise? Air restriction?
