Want this question answered?
It is not legal to modify the emissions sytem in any state. Doing so is a violation of Federal Law.
no. the catalytic converter system is there for a reason. it is reducing the impact of emissions on the environment.yes. you can but your vehicle may not pass emission standards in your state check before you remove it.
If you live in a city, state or country where emissions checks are mandatory to renew registration. Then removing your catalytic converter will make it impossible to renew your registration.
Depends on the state I would guess. However, the cat back should not have any effect on the emissions of the car. That is controlled by the catalytic converter among other things. HTH.
Sure, until the Feds or the state catches you. Modifying the emissions equipment on your vehicle can result in a serious fine.
All vehicles registered in, or commuting at least 60 days into, Bernalillo County are required to pass an emissions test every two years. Part of the emissions test is a visual inspection to confirm that the vehicle has a catalytic converter(s) installed. Outside of Bernalillo County, state or local laws do not (as far as I know) require catalytic converters, but Federal law may prohibit you from removing your cats from your vehicle. Federal law requires all cars as built after 1975 to be equipped with a catalytic converter.
yes, of course it will. They are the exact same. California wants the converter companies to pay them extra money to the California Air Resources Board, so they can put a stamp on it saying "california approved".
The lead will destroy the catalyst in the catalytic converter and the car may have trouble passing a state emissions inspection as a result. It only takes 1-3 tanks of leaded gasoline to render a catalytic converter completely useless.
Yes, it is illegal to operate any vehicle that came equipped with a catalytic converter from the factory with it removed.
Yes, it is illegal to remove a converter in all 50 states.
Yes, you have to have a catalytic converter in every state if the car came equipped with one when new. It is against federal law to remove one.
The best way to improve fuel economy it make sure your tire are inflated to the factory specification (there should be a tire information placard on one of the doors). Beyond that, making the engine breath better will also have marginal benefits. You can try installing a less restrictive air intake system, and an exhaust system with wider pipes. If you live in a state or country that does not do emissions testing, then you can remove the catalytic converter(s), which are a huge restriction. If your car has to go through emissions testing, then there are hi-flow converters that may work. The above answer is correct except the part about removing the catalytic converter. First of all removing the catalytic converter is illegal. Secondly modern engines equipped with fuel management systems will not run properly with the catalytic converter removed. Do not, remove your catalytic converter.
