Exhaust System Components
Common Components Of Heavy Duty Exhaust Systems
Bent Tubes & Elbows For directional changes of exhaust flow in exhaust systems. Available in common angles (90°, 67° and 45°) for both O.D. and I.D. tube connections.
Hanger Secures the muffler or pipe horizontally or vertically to chassis or side of cab.
Reducers, Connectors & Expanders Shorter length tubes used for connecting two other exhaust pipes of different diameters or the same diameter. Spark Arrestor An exhaust system add-on used to capture sparks emitted from internal combustion engines through the exhaust system. All Donaldson models are U.S. Forest Service approved. Splitter Tee Adapter An adapter pipe with one inlet and two outlet tubes used to convert a single exhaust system to a dual exhaust system. Stack or Tail Pipes Vertically mounted outlet pipe; available in curved outlet or straight squared configuration.
Wye Connector For joining legs of dual manifold outlet to form a single exhaust system. Wye connectors can provide an additional 3 to 7 dbA exhaust noise reduction over that of the primary muffler and may also be used to replace conventional wye pipe.
Resonator Secondary noise reduction component that generally provides 2 to 3 dbA additional noise reduction.
Tubing (Straight or Flexible) Straight or flexible tubing for connection to muffler or resonator. Purchased in standard lengths and cut to size if needed. Muffler The primary component in an exhaust system for engine noise reduction.
Note: Super stacks also available that can offer an additional 2 to 3 dbA noise reduction with no back-pressure penalty .
Exhaust Filter or Emissions Device Traditional exhaust systems with mufflers are transitioning from noise reduction devices to emissions reduction devices to meet federal and state regulations. The primary component in the emissions device converts or captures exhaust emissions to reduce overall engine emissions. An emissions reduction device can be an add-on installed into the existing system or a retrofit muffler replacing the original muffler.
Stack Cap Moisture protector used on vertically mounted mufflers or stack pipes. Clamps Exhaust systems use a variety of exhaust clamps. Selecting the proper clamp for the job is critical to a strong, reliable joint connection. Common types include u-bolt, band Clamps, bent bolt clamps and v-band clamps.
