Is it worth changing my exhaust on a 2006 dodge charger rt?

[Derrick W3749]

I own a 2006 dodge charger rt with the road and track performance group package. As most of you know the road and track package has slightly different exhaust/intake which gives it a extra 10hps. I'm was thinking about changing the exhaust on it, but i don't know if it's really worth doing considering it already has a upgrade exhaust (which is quiet but is ok with me).
