For example in the N54 world, our GC exhaust manifolds outflow stock by a significant margin, we end up making the same power as stock frame designs with a couple of pounds less boost. Less restriction.
Remember, an engine is just an air pump.
All else equal though, removing restrictions is free power.

Thank you! I get frustrated when people say/think this
