Possibly, does not necessarily mean you will lose HP though...

if u go to a more free flowing exhaust, then yes u will loose boost. but boost is just a restriction of air so when u loose it after exhaust, that means more of it made it in the engine resulting in more power, so yes less boost can mean more power.
