Cummins exhaust systems direct gases away from the engine efficiently. Turbochargers boost air intake using exhaust energy. Exhaust manifolds collect gases from each cylinder. Aftertreatment devices reduce emissions and pollutants. Catalytic converters and particulate filters clean exhaust flow. Pipes and mufflers control noise and backpressure. Cummins engineers systems for durability and emission compliance. Proper design enhances engine performance and fuel economy.
