Mark;
That was going to be my next question..!! concerning the stingers, hopefully i won't have to do it, didn't know whether it would create to much back pressure.
A correctly propped engine and a few lessons in good throttle management should help quieten things down a bit...!! [sm=thumbup.gif][sm=biggrin.gif]

Closing off a stinger will grenerate some back pressure, but it won't cause a problem. You can also go to a THREE Blade prop. That will hold the RPM down, noise down, and keep vibration down. Plus you'll get a better (smoother) idle. I use a Menz Ultra 20x12x3.
