JHM Headers

So it seems the S8 I purchased ...being an east coast car for the last 15+ yrs has developed a hole in the exhaust on the passenger side. It is somewhere between the header runners and the cat - sounds like a tractor/diesel

SO I am thinking of replacing everything...originally I was going to just have a dual SS exhaust built but with this development I might be forced into doing the headers as well with high flow cats...etc as per C5/Allroad mod list on JHM website

Has anyone done the headers on their S8? It a custom tune a must or will the 034 or UNitronics out of the box be sufficient or is it evan necessary?
