Not Ranked
So I notice that the exit in the picture shows a flat surface with two exit holes. What you are hearing is the air hitting against that flat surface when it sucks back.. ill bet on the overrun it's worst. not to mention that those welds are kak and probably make some of the noise. Why spend money on big flow valves and heads and cams and have such a ****ty exhaust. I'd post pics of mine but it's a nightmare to get a picture on here . Brent , I would have thought you would have fixed this by now cheez.
