"WebJun 28, 2024 · Most race engines use an RPM bandwidth of 3,000 rpm or less. If the primary pipe scavenging effect overlaps this band, then it matters little that one pipe tunes as much as 1,000-rpm different from another. Since this is the case, pipe lengths varying by almost a foot have little effect on power. " - Scavenging effect in engine
