exhaust leak Question

[Royawest]

Hi, Ive got an exhaust leak between the pipe and the manifold.I tightened the bolts and it still leaks. I have had the pipes off twice while changing clutches other parts and never noticed if there is a doughnut gasket on the manifold to seal the pipe. This seams to be the problem.Can anyone tell me if there is a gasket there? By the way This is for my 94 Mazda B4000.
Thanks

There should be a doughnut gasket in there I believe.
