Those deflectors I just mentioned above are bolt on. You will have to drill three holes in your muffler. I have not seen a muffler that has already been modded for sale. But I guess if you do enough searching any thing is possible.

I could mod one for you but I'd have to buy it from the dealer. Then you have to pick what style outlet you want and where. There's others who could do it that may have a 562 to mock it up on.

Thanks for the replies folks.
With all the talk on here about muffler mods I kinda thought some outfit would be selling modded mufflers ready to bolt on but I guess not.  I should probably leave it stock as long as it's under warranty.

Bump for weimedog
Watched part of your 562 video on YouTube. Around page 6 EHP talks about heat in the motor from slow exhaust flow. The one I worked on I cut the muffler in half. I used a cut off wheel. Saw is still in service and has not had any problems. Hope it helps

I don't remember exactly. But it was not that bad.

It does... By removing that internal baffle....that's a huge change! Which carb does it have and I guess obviously its not too lean...always worry as I don't really see a way to change the carb tune.

Don't remember which carb as it was a couple years ago I worked on the saw. No lean running issues. The guy that owns the saw would have locked it up by now if it was. I asked the same question if the auto tune would supply enough fuel and a bunch of folks said yes to a muffler mod and more.

the problem is a heat problem, the piston is growing faster than a normal piston in a normal saw like a 357, 372 so as the piston heats up to the point where the piston grows more than the steel pin so the pin comes loose , this can be caused by more than a couple things BUT the biggest thing is the muffler is choked off to the point the cylinder is running real hot , just feel the air coming off the flywheel on a stock 562 after a long hard cut , its real hot and in my small mind its to hot to last , my ported 562's run alot cooler than a stock 562
