Federal and state "anti-tampering" laws regulate modifications that affect emissions from motor vehicles and prohibit the sale, installation, and on-highway use of any add-on or modified emissions-related part on any pollution-controlled vehicle unless the part has received an exemption from the California Air Resources Board ("CARB") or is considered an exempt or replacement part. If a part has a California Executive Order Exemption (aka an EO #) or meets the requirements for an exempt part such as a Cat Back Exhaust system or is considered a replacement part, it is legal for sale or use in all 50 states. We are required by law to inform you about the legality of parts that we manufacture and sell and will refuse the sale of certain parts if the following requirements are not conformed with. Use of non compliant parts for purposes other than stated can result in a citation, fines, and/or confiscation of the vehicle. For the ordered parts listed below, you must certify, by clicking one of these boxes that you are using the product in the manner stated and for the application as specified by the manufacturer.
We cannot sell this part for use on a 1975 or Newer On Highway vehicle. It will not be added to your Cart.Continue Shopping
