Get an Exhaust Brake for your 2001-2004 Chevy/GMC 6.6L LB7 Duramax to enhance your towing experience and help reduce wear on your service brakes. Electronic exhaust brakes utilize the vanes in a factory-equipped VGT turbocharger and mechanical brakes use throttle style butterfly valve to block exhaust flow and create engine retarding horsepower to slow the vehicle. Available for stock and aftermarket turbochargers, turbo-mounted and remote mount brakes will fit in a wide variety of applications. We carry premium products from Banks, BD-Power, and Pacbrake to fit your needs.
