Stihl Chainsaw

   / Stihl Chainsaw #82  
Want a better built cover and proven better even on dyno. Egans straight shots. IMO.
For some reason I didn't think Egan was making one for the 261 yet. I own a couple of his mufflers and really like them. I also like that he dynos the saws and shows you exactly the gains from them. People woul be really surprised if they knew how much power these muffs add to a saw.

Does anyone make an exhaust like that for huskys?

Dude you should hear my Echo 2511 with the Egan pipe. It sounds like a moto-x bike from the 90's. It's one wicked little saw!!!
I’m not sure if I want louder. I would really like more free flowing, but with that usually comes more noise.

I'll admit my saws are all bone-stock. Despite having spent most of my younger years building engines and hot rods, I've just never bothered touching my saws... but I've always been "saw mod-curious".

The thing I used to see so often with cars, would be guys putting a free flowing exhaust onto a stock engine, wrongly thinking they'd gain something from it. The trouble was that their OEM intake, cam, and even carb or ECM were all set up for building low-RPM torque for around-town driving. By making the exhaust mod, these guys would lose the back-pressure required to maintain this low-end torque, with the obvious goal of making up for it at higher rev's, but their intake side of the engine as all too starved to allow the free-flowing exhaust to actually provide any advantage at higher RPM. Guys would spend money on these exhaust systems, and their car would be louder and feel more exciting, but very little actual time and speed was gained at the track... if any.

Maybe saws are different, if the bottleneck is entirely on the exhaust side of the engine? Can a muffler mod alone really make much of a difference, without also making changes on the inlet side of things? I am definitely not looking for "louder" from my saw, just for the sake of noise, they're already too loud to let me hear my audiobooks while cutting. :D

I understand. I don't wear hearing protection and it doesn't bother me a bit. it's not obnoxiously loud but that may be different for you. But I thought you wore those fancy Bluetooth ear muffs? :p

Here is a dyno of just muff mod on 261.
