Anyone using a DT y-pipe and have issues with smog? I know they now include resonators that look like it could take the place of the secondary cat converters visually. I'd like to work on tucking the skids so I'd like to confirm there are any issues or just modify the OE y-pipe. Also, I haven't been to a smog test for a couple years. For our obd2, no more sniffer test correct? Only visual/electronic check?
