2.0L engine 4-2-1 - manifold outlet is 3". Back part of exhaust is now 2 1/4" straight through. Having said that the manifold 4-2 joint was blowing gaskets because of the back pressure from the old exhaust. It is likely that this is where the leak is if that is what's causing it. I'll have to check that out. Thanks.
