I don't think ANY pipes and/or airbox elim kit will net any more than 5-8 rear wheel hp over stock (stock meaning hp at the wheel, which is in the low 50s, yes low 50s).

These aftermarket guys are very optimistic. VERY.

A bonnie with stock internals and every aftermarkey bolt-on gizmo you can think of (airbox, exhaust, pro-com, etc) with the exception of carbs will at most match the stock claimed hp output (around 60-65) at the wheel. AT MOST!

Did I say at most? Yes I did.

There are guys with the 904cc kits running less than 70 hp, with modified airboxes, and pipes.
