On the subject of backpressure, here's a real interesting link that I found while digging around on the 'net during ChinoCharles' Megan header dyno stuff. Explains why a less restrictive header/exhaust component seems to decrease lower-RPM power. Guess what?? Its NOT backpressure!!

Exhaust: The straight scoop on backpressure <-- awesome! must read!
Exhaust system backpressure <-- another good one.
