    Cat Question

    On the 03's we have that 02 sensor right before the cat. Will one of those carsound cats with the 02 sensor bung built in work for the 02 sensor? Or would it be better to get a 02 sensor bung and weld to the pipe before the cat?

    This is a 3 inch one....I think I'm going to get 3 inch exhaust all the way though. I'm still debating between 3" and 2.5"
