I passed the MD smog test with a gutted first cat. No problems.

Not really sure. There have been a few members out here that have gutted it out but haven't been through smog yet. And this is the main reason mine isn't done as of yet.

also if you have an 07+ it will be different because the manifold cat is now the main CAT i think.
