Muffler mod etiquette.

I guess if you don't value your hearing, open it up! After all, you all refuse to wear hearing protection, right?
Talk to an old logger, if they can hear you.
Over 40+ years working on pro saws, it is so true.

One that came on this new to me 359. Corey does slick work.

Brian aka timberwolf did a whole thread here years back with testing and his dyno back in the day here on a 026. You can go super big before any issues arise.
Just search for thread. it will open your eyes for no believers.

Heck seen 18-23% gains just on 30min muffler mods on 290-390. Those are really choked bad. 290 worst.

038 is another saw that’s pretty choked up. I removed the internal baffle on my 038 mag and added an additional outlet on flywheel side. Used a 034 muffler spacer on the inside to add rigidity to the gasket sealing surface after removing the baffle. Turned out really good and saw runs much better now.
