Faithful reproduction of the Audi RS2 exhaust manifold / cast manifold (pulse-charged manifold) for all 2.2 5-cylinder 20V Turbo — with K24/26 flange, made from D5S material (as per OEM specification).
Tested for power outputs up to 500 hp (higher power outputs are possible with additional modifications). The fitment accuracy of our manifold matches exactly that of the original part. The advantage of this manifold lies in the routing of the individual channels. In the S2, S4, S6, 200 20V and Ur-Quattro, manifolds are fitted where the first and fifth port / cylinder are routed towards the wastegate first, which results in significantly worse throttle response and also reduces maximum power output. With this manifold all five ports feed directly into the turbocharger turbine to spool it up faster and accelerate the exhaust flow. As can be seen in the detail image, the exhaust gases are slightly channelled within the manifold — as with the original manifold — and directed towards the turbine, which represents a significant manufacturing effort that many suppliers omit. The tactile quality of the manifold — i.e. the casting quality — is absolutely comparable to the original part. No sharp edges, casting defects, or porosity. The improvement in performance is clearly noticeable as a result!
