I've been thinking about going to dumps. Even if I made the switch, I'd still put tailpipes on for the smog test. Why chance it when it's only every 2 years? Some techs are so picky, they're just looking for an excuse to fail you.
On my most recent smog, the tech couldn't keep the rpm in the allowable range on 2 or 3 tries, so the computer wouldn't allow him to continue.
