For other members with aftermarket exhaust. have your oxygen sensor gone bad on you thus far? I just dropped my car off at the dealership to have the oxygen sensors replace, this is the second time since I got the exhaust installed.

Wondering have other members experience similar Oxygen sensor issue after they installed their exhaust.

My dealership is pretty nice and they'll cover the sensor under warranty. But when I asked them what cause the oxygen sensor to failed. They said its the aftermarket exhaust, but they couldn't explain to me exactly what is causing the sensor to failed.

I have the Supersprint Race exhaust, with factory headers and Cats. THe oxygen sensor are on the headers, so I don't see how the exhaust section is causing the oxygen sensors to go bad.

Any ideas?
