I used dryr hose for my first iteration and then black pvc for the second. Dryer hose will not retain as much of the heat it s exposed to. Relatively thick PVC walls will hold heat, once the car engine gets hot. I think that helps. Also, I drew heat from directly above the catalyst. My upper grill is entirely blocked, my lower grill is maybe 80% blocked, and when I had the WAI still, the remaining airflow was ducted through the cooling radiator. That kept the blast of colder air from washing over the WAI tube and CAT as much, I think. Maybe as a result of these decisions I know I saw a delta greatest than yours right now... maybe 20*F or 30*F.
But my WAI has been disconnected and sitting in my garage for two years. I have been thinking of reinstalling again.
