Long tubes/Hi-Flow Cats
What gains have you "Hi Boost" [12-14 lbs] guys seen,both in terms of HP/TQ. #'s and in 1/4 mi. times?
Also i've been told swapping out a smaller/lighter front wheel/tire combo is greatly beneficial because of the weicht of the HD 20"ers.
I have a set of 17" alloys off my Expy sitting in my shed.

Anyone??
I've searched and seen mixed results.
It would appear those with little or no mods don't get much in the way of gains.how about those running 14+lbs and already over the 400/500 mark?
