Sinister Diesel - Exhaust Brakes for Cummins

Enhance the Performance

Improving your Cummins diesel truck’s stock brakes with aftermarket exhaust brakes is one of the easiest ways to enhance its overall braking performance. Designed to make braking easier when your truck bed is heavily loaded or pulling a full trailer upgrading your exhaust brakes will reduce wear and heat to the conventional brakes. Adding exhaust brakes provides assistance with deceleration allowing you to better control your Dodge Cummins downhill speed as well.
