Does anyone make aftermarket/mod mufflers for stihl?

[nch209]

Are there any companies that make aftermarket mufflers/exhaust for stihl saws? Particularly the new 261 and 362 saws? Plan on buying one, and want more bark. Or does everyone just cut open the stock ones? Thanks in advance!

I read somewhere the Existing are normally opened up, & the newer ones are more aggravating to do, but I’m no Expert.

I have the latest and greatest MS362C-M. I don't know if the US version uses the same silencer/muffler as the European model but it's an extremely loud saw from the factory. Stihl says 119db and I can tell you when I cut with it people keep their distance and their fingers firmly planted in their ears, hence I would advise against tampering with it. More noise may be cool on paper but not when you have to work with it several hours at time.
If however the US model uses a different, more restricted silencer your best bet would be to use the Euro model muffler.

Do you know if your muffler has a CAT? I would assume the US model with their emissions regime would require one to comply Don't know for sure though;As you say prolonged use with a "LOUD" bit of kit gets tiresome my current No No would be a LOUD saw running with Sihl ultra oil mix the noise kills my ears & I can't stand the smell

They don`t have a CAT, the engine uses the stratified scavening technology and that`s why no cat is used in the muffler.

Randy has told me the US version doesn't have a baffle. The versions I have seen in Europe have a baffle, but it's a short one. It basically acts as a partition, forcing the exhaust gases forwards to the front of the muffler, then back to the exhaust port. When you remove this baffle and enlarge the exit, it makes a huge difference. The exhaust gases have a direct route to the exhaust port of less than 2 inches. It massively increases scavenging.

Another thing I've noticed along the way is with most chainsaws, opening up the muffler as close to the cylinder exhaust port as you can improves scavenging the most.

I don't know if this may be of any use to the OP, but the silencer on my MS362C-M (manufactured August 2016 in Germany) is stamped 1140/06B SDC on the left side and the two halves are not welded but pressed and held together by four bolts, I take to make the silencer easier to clean. I can provide pictures but I will not remove the silencer from the saw... if it ain't broken don't fix it, if you can't fixt it don't break it!

@little-al I cannot stand Stihl oil of any kind. It smells awful. The best smelling stuff is Castrol Power 1 Racing 2T but if you cannot find it on sale it's rabidly expensive so no thank you. I'll stick to Repsol which is JASO-FD rated and at least has pretty much no smell. Oh, and it's really cheap.
