Mack Exhaust Pipe
What is a Mack Truck Exhaust Elbow? A Mack truck exhaust elbow is angled or bent piping used to guide reaction exhaust gases away from a controlled combustion inside an engine. The entire Mack exhaust system works together to get the engine gas fumes from the engine to the outside air using many different types and angles of pipes.Depending on the overall Mack Truck system design, the exhaust gas may flow through a wide array of exhaust elbows below:
How do I choose the Type of Ends I need? When purchasing Exhaust Elbows, please make sure that you are getting the right size and have the Ends of the Elbows figured correctly.
You can think of the pipe with an ID end as being the Female end of the Pipe, and the OD ended pipe being the Male. The OD will fit inside of the ID.
- ID = Inside Diameter
- OD = Outside Diameter
Don't forget your clamps to complete the job. Most any clamp will work, it just needs to be the same size diameter as the exhaust pipe you are purchasing.
