    This has probably been done before but if it has I cant find it.What is the purpose of the valve (flap) in the top exhaust pipe? Is there a benifit in disabling it ,if so what is the best way to do it?To me it just seems to send the gasses to one pipe when you go above idle does it do anything else?

    I take it then that I am not the only one who does'nt know?
