Old Dirty Feta and the MS500i--the Hi-Tech Wood Lobotomizer

This is my current mod to the muffler. It's not final in any way and can be opened even further to allow more flow. It's probably 30-40% larger than stock.

Not a ton of room to add outlets, but I can squeeze one on the driver's side front cover. I think I have a SS red97 deflector somewhere.

I've also got some SS thin wall tubing to make an outlet on the side of the front cover. Not gonna put an outlet on the front...not my thing.

Just keep in mind that a suppressor and a muffler have two different missions. A suppressor is maximum retention of gases and maximum cancellation of pressure waves, with very little regard to back pressure(except in some automatic weapons cases). Whereas the muffler is on the backside of an engine, and it has to be tuned to that engine, with respect to pressure levels inside and out, and EPA laws highly regulate this affair as well.

Here's a few suppressors I've owned back in Texas:

I may have a larger opening on the 261's I do. Loud, tho.

My 044:

And my Echo CS361(36cc) has a huge exhaust for it's size, and it freakin loves it.

I generally go over 100% on exhaust deflectors. I do try to add baffles to tame the sound.

The more the gasses have room to hit each other before exiting, the better the sound reduction.

Think about the fancy suppressors above and then about a large long oil filter or soda bottle on the front of a gun. If you create enough area, it can match or exceed all the performance of the little suppressors.

That’s the reason Stihl puts their deflectors all the way on the back of the cans now. Even their classic front outlets always had a turn on them.

Dan, there is room on the Fly side front half (past the flange) for a deflector. If you think it out, you can add one that you modify with a small inner deflector welded to it. That way the waves must hit the front cover and bounce back before the exit. That’s where I add them on the 261/361/362. Just use rivet nuts. Trying to weld anything to whatever type of stainless Stihl uses for those cans is an exercise in frustration.

It’s all about noise cancelling without restricting flow. You can’t get a pipe effect with a muffler.

Dan would you consider modifying the curve a bit. It certainly would effect in a better quicker escape route. The way I see it there must be a bare minimum of gas obstruction.
Of course keep in mind not to direct them upwards , i ve learned the hard way almost melting a brake

I dislike when the serial number plate gets dark and burned from exhaust in that location.

You are far more educated and you are building wonderful saws. My question is why in their strongest saw the 661 there’s just a baffle with straight exit, moving gasses straight to front wall and not angled at all. So gasses exit straight to the front kinda “spaying” the can. The velocity should be so high that maybe returning gasses are absorbed by the exhaust port.
Sorry for bold just saving time to type on phone screen.

But the saw police cannot give a ticket about that...lol

wouldn’t be that way if you didn’t Valdez the Saw mix

Lol. No they cannot. Lol
