That's what it was last time with the K&N on so hopefully it'll have a few more this time *fingers crossed*

if you go by the old rule of thumb
long pipes good for mid range(torque) but suffer at top end
short pipes good for top end but torque suffers
this is good rule of thumb for intales and exhaust manifolds, long pipes give momentum to the moving gas so help with filling cylinders at close to top dead centre when the piston speed is very slow. on the negative side there is more frictional losses in long pipes so there are some losses at top end with long pipes especially if there are bends in it.
