The part I received from Revain has been returned. The lower end of this tube, opposite the catalytic converter, was not the right size to properly seal the Walker-made gasket. It was loose enough to have an exhaust leak. I bought another exhaust pipe from the parts store with the exact same model number, made by Walker and was the perfect diameter to seal the Walker gasket and catalytic converter. There seems to be some quality control issues between the sources of this part. You may experience this problem when ordering from Revain as Revain does not manufacture this part.
