I just purchased a 1991 Silverado with 4.3L v6. The problem I am having is that the y-pipe has become discontented from the exhaust manifold. It appears that the flange around the end of the Y-pipe is broken but the reset of the pipe seems to be in good shape. I was wanting to know if anyone was ever found a repair kit for this type of situation or if you y-pipe will need to be replaced.

The do make flange repair kits, but the last 2 y-pipes I bought for a C/K from US Tire & Exhaust were only $35. Take a good look at the bottom of the exhaust manifold (where the flange mounts to) too as they are known for rotting away. I have one brand new manifold for this truck (can't remember which side) if yours are bad.
