How it is possible? I see just 1 hole on both sides in photos. Or is it possible to order ae86 manifold with drilled holes for blacktop?

Is there information how loud is competition exhaust system?

No redrilling. No separate order for blacktop. Marko (Martelius) informed me both manifolds fit 20v blacktop head. Probably the holes allow for exhaust-manifold to port alignment. (Tuners like to experiment with alignment for torque curve manipulation.)

I will ask Marko for further details about the manifolds and loudness of competition system.

But loudness of the exhaust system is largely dependant on engine power output (volume of gasses) and gas speed through the exhaust exit. (Turbine of turbocharger acts as sound-damper so turbo cars are usually more quiet.)

So any data collected on one engine does not give you good data on a different spec engine.
