1. Exactly which part of the "smog" system do you want to remove? None of it has any effect on HP.
2. Everything has to be there for emissions. Its all part of the complete system. You cant change or remove any part of it without effecting some other part. If you dont know exactly what you are doing you will likely make things much worse.
3. first off that engine was designed with that equipment in use. by removing that equipment , you will be changing the way that the engine runs and possibly in a bad way. the smog system itself ties into many different subsystems as i see it. ignition is set up so that you have a flame that hits the cat and heats the catalyst, the exhaust is set up to contain that cat, the efi is set up to compensate for varying loads and driving conditions. all and all, of you want something with out smog, go buy something from the 60,s
