Exhausted

Only a small rusted exhaust came with the mower motor. It's really loud and might anger neighbors, so i tried making a new, quieter one.

There's many types of exhaust styles. There are high-tech noise cancellation mufflers, but the one i chose, which was also the simplest to make was just a straight baffled design. That's where the inner pipe is drilled out and insulation is wrapped between that and the outer shell.

Here's an example of the basic ideas i tried to follow
After removing the old exhaust i connected steel plumbing pipes.

Here's what the inner pipe looked like after i drilled out the holes
Then wrapped it with steel wool and fiber glass

Here it is on the mower. I'm still working on it because it's still pretty loud.
