I think it's in your head. I don't see how the turbos will spool up slower if you have better exhaust output, meaning, both exhausts open vs just one. That just doesn't make sense. If you look at after market exhausts, they don't have the valve at all and have better output, they actually increase hose power slightly. Racecars just have straight pipes no valves. Check this out

however just opening up the flap you will not see as much gain as the above. Maybe guessing 1 HP increase
but the sound rocks, I love it.
