Hooker exhaust?

This is good and dandy, except, that unlike the water hose, the gases do not always have constant pressure, higher RPMS give the gasses higher pressure, So in Essense, at low RPM's back pressure is needed to move the gases out quickly, and at High RPM's .. Back pressure is bad...

and who races in low RPM's ?!?!? hence my orginal saying that backpressure is bad..
