Thanks for the reply. I did check their website they have an exhaust flange in 3” but I measured mine at 3 1/4 “ unfortunately. It’s the same exact looking part though. I found another exhaust flange on activewake.com for a moomba the exact part but says it measures at 3 1/2 inches. Is the measurement outside diameter or inside diameter? The exhaust elbow is 3 1/4 exact inside diameter as well. Does anyone know what the exact size of the elbow and flange are? I am only able to fine 3” or 3 1/2”. I’m thinking it could be the 3 1/2 inch measuring outside diameter.
