Bisson Pitts and os 120ax
Hi all. Has anyone had experience with a bisson pitts (the ones currently available on Tower) and the 120ax? I am contemplating using it in my ultimate bipe so that I do not have to hack away half the cowl to fit the stock powerbox muffler in there. Is there enough back pressure and performance with the pitts?
