The only way to lose power with zero back pressure is to over scavenge the cylinder.

The exhaust system works like an intake manifold with resonant tuning. so whenever you merge the exhaust pulses and/or change the dia of the exhaust you generate a different amplitude of pressure wave based on its distance from the exhaust valve
