I'm trying to get my S13 SR on the road and need to pass emission. I'm currently in the process of acquiring a 3" inlet HF cat and a muffler. Can I pass Oregon emissions with a HF cat? I also read that sniffer tests are no longer in effect? Should I get a regular cat and a HF cat for after emissions?
