Having trouble sizing pictures.
The WAI system consists of a heat shield enclosing the space between the exhaust manifold and engine block, a corrugated hose about 3" diameter leading from the manifold to a "cut-out". For those not familiar, a cut-out is a valve people put in an exhaust pipe so they can select an exhaust routing on the fly. Mainly used in racing to bypass the muffler. This allows the driver to adjust the intake air temperature with a choke cable mounted in the dash. The other side of the valve goes to ambient underhood air and the valve has, basically, infinite adjustability. I will try again with the pictures soon
