*DISCLAIMER: NOT LEGAL FOR SALE OR USE IN CALIFORNIA ON ANY POLLUTION CONTROLLED MOTOR VEHICLES

DISCLAIMER: Emission-related parts for OEM non-emission control system equipped motorcycles as well as slip-on mufflers that mount downstream of and which do not alter the performance of OEM emission related devices are considered legal replacement parts by the California Air Resources Board (CARB). CARB does not, however, permit the use of aftermarket parts that remove or alter OEM emission control devices unless certified by CARB, other than for closed circuit race use only. 
IMPORTANT: In 2021-up UK, EU, and international models Harley introduced additional O2 sensors located towards the end of the mufflers. These additional O2 sensors need to be eliminated using the Vance & Hines FP4 Fuelpak and blanking plugs. Alternatively, you can contact your local HD dealership for advice on this issue as they may be able to eliminate the O2 sensors for you.
