Hi Again Roger;
Yes it is a nice muffler, more like a exhaust diverter through, as there is nothing inside of it. I think it's going to be loud
Biplanes are loud through ,arn't they !!!
Noise at our field is no problem .
I do know about 3:1 on the air thing . The head will be showing through the bottom of cowl, and there will be some area under cowl that is removed to let air exit. There is also a dummy radial (plastic) that fits in back of cowl, and then you cut the area out that is in front of the cylinder head for air intake. ( picture is from the CD build )
When I do the cowl , I will have pictures to show what it looks like. I think the cooling will be fine.
