The shop I went to did more than take a quick look with a mirror, and the car passed every other test without mods. Did you pass the smog test with the new 'friendly' shop?Could be - and the paperwork I have doesn't show much and the modification shop is no longer in business. I doubt the guy checked numbers - he just did a quick look underneath with a mirror and sent me away. Over the weekend, a friend recommended a "friendly" shop where he gets his old truck smogged and that guy did the same thing.
