Scavenging vs non scavenging

[xlr8ngn]

Just curious. Looking at our driver's side exhaust tubes that create a collector (albeit very short) versus passenger side exhaust log design, would 1,3,5 not run leaner because of scavenging?

Scavenging is a thing for naturally aspirated engines.
The manifolds on a turbo car are highly pressurized so there’s no considerations for scavenging
