Typically less back pressure will increase both torque and HP but where in the range it depends on the engine. Typically you gain midrange mostly, lost a slight amound in the bottom and gain a slight amoung in the top.

That being said, you should never expect any exhaust to give you any substantial power gains, its mostly for sound and aesthetics.
