There are 2 sizes of Magnum manifolds. If you have the larger ones (2 1/8" outlet) I sell the bell flared connection that goes against the manifold. If you have the smaller outlet you should be able to get the local muffler shop to form the flared fitting but it probably won't be bell flared like the factory ones.
The one on the right is the bell flared large hole magnum connector.
