I think this should be put in the FAQ section so much good info here and will help end this stupid myth.
as breifly explained earlier the yamaha valve in the exhuast is not for back pressure its to setup an earlier reflection pulse for the valve overlap period. This is effectivly creating a second resonance so the exhaust pulse is sent back lower in the rev range to stop all the air going straight through because of the high overlap. Not true? the try this is a car with normal overlap and see how far u get.
I think people who say things is support of back-pressure are just people who don't understand what harmonic resonance is.
