I have an exhaust leak coming from the front exhaust manifold on my 1998 Chrysler Sebring 6cyl 2.5L coupe. I took the exhaust manifold out and there is 2 even cracks on the left and right side of the manifold (see picture below) Is this normal?

 

Your pictures didn't post up. If you suspect a crack, you could have it magnafluxed, but it might be cheaper to just replace it.
