I need a good muffler...Zenoah G-62 just sounds like a chain saw in the air...euuuugh
Has anyone yet devised an effective muffler to quiet down the Zenoah G-62? I fly a beautiful 3rd scale Cub, in a very scale like manner, and the exhaust noise from that motor is driving me nuts...or it'll drive me to electric power if I can ever afford it. I currently employ a B&B muffler....which is little more than an exhaust diverter. It's a loud thing, but it is small and cheap. I have tried expensive wrap-around pitts styles in the past, and they are very little improvement....and not worth the huge extra cost....at least as far as noise abatement is concerned. Are there any real options to rid myself of the loud raspy exhaust note?
Thanks for your comments.

There are, but a canister muffler and header is not going to fit in your cowl. If that is not important to you, it will cut the noise way down without any loss of power over a pitts type muffler.

The DA header will fit the G62. So any header and wrap around pipes you would see on a DA can be had for a G62. Check the DA website and also check the KS.

Toni Clark is located in Europe. They are the industry leader in performance parts and exhaust on the Zenoah line of engines.
Here is the current catalog in PDF format. The Silencers for the Zenoah G62 start on page #80.

Don't know why but those B&B exhaust diverters .... so called mufflers really have a nasty bark to them. I think they sound worse than no muffler at all.

Will the stock 2-pipe muffler fit in the cowl? They sound really good albeit at the loss of a little power. It is a cub afterall.

If you don't mind a little grinding and some brazing, you can cut the stock muffler open and remove part of the spark arrestor assembly. It makes the muffler louder, but removing a bit of the spark arrestor also makes it breath better and provides some mild performance boost over stock.
Just cut it open with a dremel cutting wheel. Gut it. Braze it back together with a small oxy/mapp gas torch and any mild brazing rod.

On the stock angled pipes with the two outlets, I have not seen any kind of spark arrestor-just the fact that the tubes go way up to the top of the muffler on the inside.
