Muffler mod etiquette.

[sean donato]

I know exactly how a tuned exhaust works, and how the physics do not apply in any way, shape, or form to a can muffler.

I only had 1 that was obnoxiously loud, I ended up putting a muffler Randy modded for me on it as my ears don't handle loud noises very well anymore. I am probably not the best neighbor in that department as a 15:1 open header big block on the trans brake at 5500rpm "maybe" a bit louder that any saw! But I am very careful to run it only during the day and inside the garage. A friend that lives a quarter mile or so away know when I am running it. CJ

I use to love loud motors. At 47 I have 90% loss in my left ear and my right isn't much better. I bought longer like loud noise! It sets off my tinnitus and is just annoying.

I have a bark box for my 400C. It makes more power for certain, but is obnoxiously loud.

I put a header pipe on my 261 (non-electronic) from Egan and it seems that there is a significent difference in performance, hopefully running cooler too. But like yours, very loud!

That motor has a tuned pipe. A saw doesn't not have any such thing.
What @sean donato said was spot on in every regard.

To me....it looks like Husqvarna at least tries to "mimic" tuned pipe with that pear shaped exhaust....?

There's zero reason and no evidence to support that idea. One it's a stratto charged saw. Extremely little to zero useful fuel/air mix is leaving the exhaust. 2, there is no area (s) shaped remotely like a forcing cone where you would get the reverse pressure/ sound wave to "push" any fuel/air back into the cylinder to "super charge it."
