RS2 Exhaust Manifold

Again, not the most exciting of topics, but if you intend to run much past 300HP, or if you intend to run the S4 hot and long, the RS2 manifold is cheap insurance.

Essentially, the problem is that the stock manifold is far too restrictive, especially for the #1 and #5 cylinders. The RS2 was designed with a 315HP motor in mind, and is thus much easier-flowing, and hence builds up much less heat underhood.
