Horsepower gains?
What are the horsepower/torque gains from adding an American racing cat back system?

As far as I know, American Racing doesn't make a cat-back for Mercedes, but they do make long-tube headers. What exactly are you looking at?
What are you talking about? ARH is one of the most popular headers around here.
