1G Custom built "True dual" exhaust

[NoahThePositive]

I'm planning on welding a custom built true dual exhaust (headers lead to two exhaust pipes instead of the normal single exhaust) and am wondering if its been done before and am requesting tips on welding, mounting and where to buy exhaust pipage (i'm in north eu). The first problem would be the manifold and how i should make a custom manifold and if i can use the stock manifold to do this build. I am aware that it is not the best for performance etc. but im doing this because i want to and the unique sound. Thanks for all support!
