Heres the echo all muffler modded. It really not a whole lot louder but sure breaths better. This should also help the chain cover too. it was starting to melt it a bit from the exhaust.

Did a muffler mod to my newly acquired ms341. I cracked the muffler open like an egg and removed all the junk inside. I welded the muffler back together. I drilled a big hole in the muffler and added a short piece of pipe. I also matched the exhaust heat shield, gasket and muffler inlet to the exhaust port. Gave it a coat of high heat paint for a final touch. The saw seems a lot happier now. Throttle response is great. Wot is noticeably higher now. I had to remove the carb limiters and retune it.image.jpegimage.jpegimage.jpeg

Here are a couple of muffler mods I made to my Stihl 029 a while ago. I also opened up behind the front plate.
This really woke this saw up.

A little bit. I always wear hearing protection and I am usually focused, so sound doesn't' bother me that much.

About to mod a couple 044 mufflers. Mine will have a duel port cover on it and was thinking of opening the factory hole to the size of the deflecter on the side. Any ideas?
The 288 husky deflector fits on the lh side for a 3rd port ,and can still run a screen .hybrid jug clearance 015 muffler small.jpg

Little husky 136 I am servicing for a friend
Original port was so small it looked like a crack in the steel.
It now has dual ports and a skeletal baffle

Currently baking on some fresh high temp black paint
