I'm in the middle of doing a "spend no money" rebuild of a 2007 Outlander Max that I've manage to score for our hobby farm.
The muffler was rotted out around the drain plug, so I figured I'd just rebuild it.
I really don't like the noise of the after market mufflers.
Thought you might be interested to see just what's inside a genuine muffler.
I carefully cut away the rotted skin to reveal the inside components.
I then made a new particulate capturing chamber out of some sheet steel and pipe.
I then rolled a new outer skin from an old computer tower case. Welding slots were then cut in the correct locations of the components and a new bung hole.
Then all the componets were placed in the new skin and tacked in place.
Before I weld the front section back onto the muffler I have to finish putting new timing chains in the motor.
I'll post a finished pic of the muffler when I'm done.
