Aftermarket Exhaust FAQ's
To all of our customers,
Our sales office in Chino has been receiving a lot of requests for information regarding compliance with state and federal regulations.
As a result we are making available a document prepared for our industry by the Motorcycle Industry Council (MIC). This document is intended to clarify proper use and sale of exhaust systems in the state as well as answers some frequently asked questions about this topic.
FREQUENTLY ASKED QUESTIONS ABOUT AFTER-MARKET EXHAUST SYSTEMS FOR MOTORCYCLES AND ATVS IN CALIFORNIA
This is Motorcycle Industry Council’s interpretation of California law and regulations related to after-market exhaust systems. MIC has prepared this information in an effort to clarify related issues for dealers in California.
What exhaust systems and slip-on mufflers can a California dealer sell or install without violating California air pollution control requirements?
After-market exhaust systems that can legally be sold under California’s air pollution control requirements are (1) systems that are designated “replacement parts,” (2) systems considered “modified parts” for which an Executive Order has been issued, and (3) systems only for use on “racing vehicles” that have been adequately identified as such.
What exhaust systems and slip-on mufflers are considered “replacement parts”?
Can I install an unapproved after-market exhaust system that was purchased by the owner from out of state?
Installation of unapproved after-market exhaust systems is legal only if the systems are “replacement parts” or being installed on a motorcycle or ATV for competition use only.
