Can you guys with G62 experience help me out with muffler options?

I know of a few companies making mufflers specifically for the G62, what I am interested in, is finding out what compatibilities there are between this 62 and other brands in the 50-60cc range that will bolt right up. This info comes in very handy when shopping in the classifieds or at swap meets.

I'm hoping to find something small, light, simple and not too restrictive as far as in cowl stuff goes...for example, has anyone mounted up a DA 50 muffler on their 62...etc?

Any advice you can offer will be great, thanks!
