My 1998 Blazer is leaking all along most of the y-pipe or crossover pipe that comes from the exhaust manifold flanges and leads to the cat. Where the pipe bends lies the biggest problem; a crack which runs parallel with the pipe and along the outside of the bend. has anyone else had an issue like this? I have looked on summit racing and jegs and can't find a replacement pipe.
