I ordered the Turner mono ball arms for the front and am trying to decide what to do with the tuning. Tune as is with stock M5 manifolds, cats and E38 stock exhaust cats back or go with headers, custom exhaust and then tune for maximum performance. Just not sure how far they can take it with the stock stuff. I would upgrade the fuel pump no matter what. My biggest problem is that although I thought I wanted a more aggressive exhaust tone, I have really grown accustomed to the silence. Which also makes it a better sleeper.
