2011-2016 GM 2500HD/3500HD 6.6L LML Duramax Exhaust Brakes

An exhaust brake is the perfect addition to any 2011-2016 GM 6.6L Duramax LML that is constantly towing or hauling on a regular basis. Exhaust brakes work by trapping engine pressure inside of the exhaust system, creating more backpressure which causes the engine to rotate slower and stops your vehicle sooner. This takes additional stresses off your Sierra/Silverado's factory braking system which helps out with the overall longevity of your truck. Keep your truck running in great condition with y one of the aftermarket exhaust brake systems we offer right here at Alligator Performance!  GM Duramax Fitments: 2011, 2012, 2013, 2014, 2015, 2016 GM 6.6L Duramax.
