ECM units on fuel-injected models need to be recalibrated if used with free-flowing air cleaners and/or modified engines. Muffler shells may discolor if ECM units are not calibrated correctly.
These mufflers are designed for use on closed-course competition motorcycles only and do not conform to U.S. EPA noise emission standards.
The California Air Resources Board (“CARB”) does not permit the use of aftermarket exhaust systems that remove or alter OEM emission control devices unless certified by CARB, other than on racing vehicles on closed courses. Check your local laws and manufacturer's information.
