or will your car not pass the sniffer portion? I never understood why people have so much trouble passing the sniffer test. I have a relatively heavily modded Z and only run the 2 main cats for smog. I also live in a strict county that requires idle, 15mph and 25mph tests on rollers and I've never even come close to failing the sniffer. It's getting them to overlook some of the visual stuff that's the trick.
