Will it hurt to run my 18hp kohler command without a muffler? I've got about 3" of pipe on each head.

It shouldn't if the engine is running rich enough. Reducing the back pressure in the exhaust system can cause the engine to lean out. Usually a simple carburetor adjustment will take care of that.

I just need to drive it two barns over. Maybe 15 minutes run time. The stock muffler will go back on after I do some welding.

:ditto:
oh, and As long as the engine isn't separate seats that can work loose, the rapid cool down of a short pipe can cause the problem to develop.

Never been in a command, thankfully...

Edit, just saw your post.

A one time thing shouldn't be a big deal.
