89070 Upper exhaust bellow

The upper exhaust hose (89090) can be installed on to 3 inch center mounted risers to 4 inch elbow, or 4 inch y-pipes with rear mounted risers on various inline 4 cylinder, V6 and V8 models. This hose is tapered, with the top end having a diameter of 3", and lower end having a 4" opening. When replacing this part, it is recommended to inspect the lower bellow (89090 or Mercury 32-90949T) which mounts below this part. If the lower piece has any cracks or leaks, replace it as well. If new hose clamps are required, use clamp 01056 on the 3" end, and 01100 on the 4" end.
