Donaldson Exhaust Muffler

There’s nothing quite like a truck that purrs with power, and the Donaldson Exhaust Muffler knows exactly how to keep things running smooth and deep. At an impressive 51 inches of finely tuned steel, this round beauty dampens the raw growl of the engine just enough—turning that aggressive roar into a low, controlled rumble that commands attention. Like a firm but knowing hand on the throttle, the Donaldson M090544 tames excess noise and vibrations while keeping that satisfying hum alive. Built tough for long, punishing hauls, it lets exhaust flow freely while keeping emissions in check—because nothing should stifle performance when the road is begging to be conquered.
