I have a MVVS 35 cc in a Seagull Edge 540 (120 - 180 cu inch size), I have done some mods to the fire wall to take the engine. I have fitted a smartfly power expander and a fiber optic kill switch. I have fitted the engine and run it on the ground (two tanks) with the standard muffler. I'm in the final stages of fitting the cowl, what I would like to know is what advantage am I going to get from using a MVVS 3268 tuned pipe on this plane? Secondly any tips on the set up and the "tuning" of the pipe would help.

Thanks for the great tips and advice on this site.
Mike
