Diesel Engine Mufflers

Our mufflers, silencers and exhaust systems reduce noise and back pressure, increase fuel economy and extend service life. As part of our expanded focus on the exhaust market, over 250 part numbers have been added to the new Donaldson exhaust catalog. New parts include 30 new off-road mufflers and a wide variety of new clamps that are easier to install and have better sealing ability.
