If you want to make it free flow, you will have to take it off and pound out the insides. But if you have to pass a smog test, it will fail. If you need to pass the smog test, the best place to find an affordable replacement is Rock Auto. If you live in a state that has no road salt, the best place would be a local junk yard........
