California Proposition 65 & CARB Law Policies

CARB Emissions Notice

The state of California considers aftermarket exhaust systems to be legal replacement parts for non-catalyst equipped motorcycles and/or if slip-on mufflers are installed downstream of the OEM catalysts.

California does not allow the use of aftermarket systems that remove original equipment catalysts, (except for racing use only) unless the Air Resources Board has issued an Executive Order for that system. It is the customer's responsibility to obey and follow laws, rule and regulation that pertain to your state, region or municipality.

About Proposition 65

In 1986, California passed legislation called the Safe Drinking Water and Toxic Enforcement Act of 1986 that entitles its residents and consumers to receive special notifications about products known by the state to contain chemicals that cause cancer, birth defects and other reproductive harm if the exposure to them is above specific thresholds, so that they can make informed decisions about using them in their home or work environments. Today this legislation is commonly known as Proposition 65. Because our mission is to help you make informed decisions, and we care about your health and wellness, we are providing the following warning for products that link to this page:

WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
