I think that in theory it should but doesn't look that Toyota is differentiating HP between TRDP and others.
Thoughts?

Generally speaking... yes, cat-back exhaust systems have the potential to increase power gains. That said, the general consensus (at least in the tuner world) is that that parts are only a part of the equation, the engine/ecu tune more often than not needs to accompany it to really unlock that potential.
So in my mind, intake & exhaust without a tune just make noise, but some people just like to sound fast.
