Absorption Muffler Models

The below are the part and drawing files for each of the 5 absorption muffler configurations.

All of the files were made using SolidWorks. It is very important to save the part files and then open them in SolidWorks.

The Sine and Cavity configurations each have two solid model files. The first is what the muffler was designed as and the second is what the actual geometry was.
