Re: Measuring stock exhaust restriction
Yours and mine both have been opened up about 2mm or so, along with reshaping/contouring. Be nice to see what actually happends pressure testing on a bench.... wish I had some aluminum here as I could compare to totally stock too. I guess I wont waste more time entertaining ideas of increasing flapper size..... too much influence on opening pressure per the math.
