Water leaking from exhaust pipe

[Xhawk101]

Hello I just realized I have a small exhaust pipe water leak apparently at the elbow where it connects to the Grey rubber muffler. I tried tightening the clamps but no better.

Any suggestions or advice is greatly appreciated!

I would suspect a pinhole in the elbow.
Time to take it apart and see what is what 🙁

The casting is the thinnest where the hose connects to create an indentation for the hose clamp to suck down the hose. If you have a leak I would guess it is worn down on the inside from gallons of water flow. A major crack or break is imminent. Time for a new mixing elbow.$$$$ easy DIY fix. Pre 70s cars water pumps would leak the same spot, if they lasted long enough to wear through.

My two cents!

Good luck!
