Yes you are right but its still restrictive, I put a set of Jardine on my R3 while I was doing some work on the Rebands and noticed the difference at higher RPM.Isn't the key improvement with the Jardine and other better headers is that all 3 pipes merge into a single cone collector rather than #2 and #3 entering the pipe from #1 at 90 degrees with the better ones having bigger diameter and equal length pipes to the collector with torque and power variation also affected by length of pipes from head to collector?
