Remember too that cup cars from 964 to now (though I do not know about the 992), all had at least one operable resonance flap.
I had 993 plastic intake with single throttle on 3.8 rsr enduro pistons and factory rsr cams 1.75” headers and res flap makes a difference. Though that intake was too small for the motor...
