exhaust for a B31 with gas 454's

Post by gcreas1 »

Coming out of my exhaust manifolds I have hose going to two fiberglass elbows that then run to a combining pipe that ties both exhaust lines together before it hits the muffler. That combining piece appears to be constructed out of iron.

Question, does anyone know if they make a fiberglass replacement for that piece? Mine look like they are ready to give out.

Thanks

Lewis marine sells them. With gassers I think you need the exhaust branch Y, 2 4" to 5 " exit. These should be easy to find locally they are a commonly used for wet exhaust.
