Has anyone out there had to deal with CARB? Bottom-line: What are the cat-back options for my 1997 4.6L Thunderbird?

 

there's no carb on those engines they are all fuel injected and controlled by the computer

 

If I am not mistaken, if the vehicle was manufactured with certain emission control devices , you cannot remove or render those devices "non functional". Your best bet is to check with a vehicle inspection station in California for smog device tests.

 

Dynomax offers a 50 state/CARB legal cat back. Probably others too..
