Running the G20 with any of the better quality and less restrictive side dump mufflers than the stock unit gives an appreciable boost in performance, approx. 500+ rpm increase at WOT.

Karol,
Do you know if that includes the B&B side dump carb for the G20ei. Also, what side dump muffler woule you recommend and what prop are you using. If I can make the G20ei work it would be great. An additional 500 rpm would be worth trying first. It is an exceptional engine, just no enough oomph for 15 lb plane. (IMHO)

Thanks
Howard
