There have been claims by some manufacturers that unequal lengths broaden the torque curve due to different cylinders performing better at different RPM. It is left to the reader to decide if flattening the torque curve is a good thing to be doing with headers. However, a flat broad torque curve makes better drivability, and a smoother power band than a peaky engine. | There have been claims by some manufacturers that unequal lengths broaden the torque curve due to different cylinders performing better at different RPM.

| + | How does one unequal length tube make for a broader power band? This sounds like someone trying to explain away poor design. So does a 180 degree intake manifold have just one shorter smaller runner? | ||
