76 Coronet Exhaust Manifold Problem

Hi Guys
My 76 Dodge Coronet Crestwood has a leaking exhaustmainfold. Is there any type of headers or arftermarket mainfolds that will fit in with the original exhaustpipe? Im from Switzerland, and its very difficult to change the exhaustsystem here because of the streetlaw. Hope someone can help

Welcome from California, USA.
The mid 70s cars often used a steel tube that attached at either the front or the back of the exhaust manifold. It was used to inject fresh air into the exhaust stream to reduce emissions. I have seen these crack and leak, giving the impression that the manifold itself has cracked. I don't think that they used gaskets at the head or at the exhaust pipe but it might be possible that someone at some point added them. They may just be worn out and leaking.
The manifolds are not hard to find here, I have several. If you choose to stay stock, send a picture of yours and someone may be willing to sell and ship to you.
