I finishing up my 84" WH Edge with a G62 and hope to maiden it this weekend or early next week. I want to wait for a Bisson side mount muffler which won't be available until early August, so I'm planning to use the stock Zenoah muffler and fly without the cowl. I don't think there is a problem doing this but just want to make sure. Comments?

The reason for the side mount Bisson is I've heard it is a tad quieter than the wrap around, provides a little more power, and is 3 oz lighter. If someone has another suggestion, I'm open.
