Recently picked up a CS-590 Timberwolf for $180 (which I thought was pretty reasonable). Unfortunately, the previous owner decided to get a bit aggressive with a dremel on the muffler.

My goal is to maintain reasonable exhaust flow while reducing the noise this thing puts out.
First thing I did was remove the pipe from the baffle in the exhaust. Previous owner just flattened it out.

Next, I tried my best to remove the dents in the muffler. Didn’t turn out how I was hoping, but sits better on the saw now.

It was around this time I found a perfectly sized piece of tube stock.

Compared to the original, the new pipe is much larger diameter and shorter.

And fits nicely.

At this point I ran out of midnight oil—more to come later.
Planning on welding it to a piece of flat stock that I can sandwich between the top of the muffler and the deflector.
