I have a royal 40
it is a good motor mut a bit loud
how can I make it quiet (realy quiet)???

Macs?
 

They have muffled tuned pipes...

I just saw on here somewhere a site where they make muffler extensions- Looks like it attaches to the back of your existing muffler with silicone tube...

Don't see too many Royals around these days, they were pretty good as I recall*

Is it a BB? Ring or ABC/AAC?

I am building a website about quieting down our models. There is still al lot under construction, but you can already find some information there.

The pages on how to build the muffler are still to be written. I already have the pictures, but it will take some more time to fill in the text.
