California VS. Non California for Z31

To be able to determine if your car is a California or Non California Emissions car there should be a sticker on the door jam, the drivers door or under the hood that will specify if your car was imported with the California Emissions. For the Non California design the converter is 14" long instead of 15 7/8" and the down pipe is also 1 17/8" longer as well. If you are replacing the converter or off road you will need to know which one you need but if you are ordering a complete system the shorter down pipe will make up the difference of the longer converter or off road. If you are ordering just the converter or off road along with the cat back system then you will need to order the converter or off road pipe that is designed for your car. If you are ordering a down pipe only we will also need to know if your car is a California or Non California design.


Explanation of Off Road

Off Road products are manufactured for vehicles that do not drive on the public roads in the USA. EPA vehicle emissions law states that it is illegal to remove Catalytic Converters or change the size or configuration of the factory system (unless there is another same type vehicle with a larger or different configuration) that you are allowed to copy. The EPA gives us some leeway with the size and configuration of our exhaust systems but they don't like you driving on the streets illegally without a catalytic converter on your car. For those of you that don't know it, you can be fined for driving your car on the street without a converter even if you did it yourself. It is a Federal Offense.
