Exhaust Brakes will help your 2020-2023 Chevy/GMC 6.6L L5P Duramax slowdown when it's critically for safety while also helping to reduce wear on your service brakes. Turbo mount and remote mount brakes are available for both stock and aftermarket applications. Electronic brakes are used in late model pickups and function by using the existing factory-equipped VGT turbocharger. Mechanical brakes use a throttle style butterfly valve to limit exhaust flow and create engine retarding horsepower. We carry premium products from Banks, BD-Power, and Pacbrake to fit your needs.
