CARB lists legal catalytic exhausts and other parts


The California Air Resources Board (CARB) has posted a list of motorcycle aftermarket critical emission control parts that have received an exemption from the state's anti-tampering laws. (Click here to see the list.)

An aftermarket critical emission control part is one that replaces an original motorcycle part designed primarily for the reduction of emissions. Examples include catalytic converters and oxygen sensors.

The parts and devices on this list have complied with the "California Evaluation Procedures for Aftermarket Critical Emission Control Parts on Highway Motorcycles," adopted in January 2009, and are therefore legal for sale and installation in the state.

At press time, only five companies had products on the list: BUB Enterprises Inc., Cycle Shack Inc., Ducati North America Inc., Thunder Heart Performance Corp. and Yoshimura R&D of America Inc.

The list can also be accessed from CARB's main webpage for motorcycle aftermarket parts:
