I'm pretty sure that all gasoline or diesel powered vehicles in the U.S are required to have a catalytic converter.
Yes, it is illegal to remove a catalytic converter in any state.
just cut it off
It is illegal to remove a catalytic converter without replacing it. Don't cut it off, unbolt it.
it is a 10,000 fine for a muffler shop in Arkansas to cut one off.Most shops wont take the risk unless you know them .but you can cut them open your self and pull out all the junk then close it back up. PS use gloves when you handle the insides
No, it is illegal in all 50 states.
Removing a catalytic converter and not replacing it is highly illegal.Removing a catalytic converter and not replacing it is highly illegal.
IN a word-YES, the computer monitors flow in and out the engine removing the cat will screw it up.
No, it is illegal to remove a catalytic converter from any vehicle unless you replace it with another one.
No, it is illegal in all 50 states.Yes you can, but then your car will not be legal and also will not pass any emissions test.
Should you cut off the catalytic converter? No. But can you and will SOME vehicles actually benefit? Yes. It is illegal to remove any emmision control device from your vehicle in most if not all states. For countries such as Mexico where it is not illegal, some vehicles without downstream Oxygen sensors (after the catalytic converter) it can have some benefits. It is really the same benefit as a free flowing exhaust. Modern (97+) cars already have a free flowing design catalytic converter so there is no benefit to doing this.
Because that is how they are made to run. They were added to cars to cut smog emissions and meet federal/state standards. Lead ruins the catalyst in the converter.
Yes, and it is also illegal to remove the catalytic converter. Your engine will not run properly with the converter removed and will have less power and will use more fuel.
In a word no, not only its illegal it will improve performance try a bigger cam or throttle body or a aftermarket ECM.
