Hi Again,

I still haven't ran this engine lost temporary interest in the hobby, Now I'm back.

I have the Mvvs 150 mounted in a 72" Yak 54. I need a Pitts style muffler to keep the fit in and under the cowl. I see from the Mvvs website they have pitts mufflers for their engines But I don't know which one to choose? Any recommendations Pe reiver?

Thanks in advance

Ron
