Thread: Modify CT70 Stock exhaust

Can any body tell me how to modify the stock exhaust on my CT70 for more flow?

Some guys have removed the spark arrester to increase flow.

Apparently that was done before I bought it.

I'm looking for info about using a hole saw or drill bit with extension.

I do have a mig welder if I have to dissect it to properly modify the muffler.
