26mm Delly PHB

What manifolds for a 26mm Delly, breathing thro' the std airbox & 22mm rubber, & still wearing un-cut side cans, are you all using?
I'm using a Beedy 90 deg type one & it pushes the carb rubber out so it gets compressed by the side can
& its restricting the air-flow
So before I start stripping I'm seeking your advice?
