AUDI S2 RS2 EVOLUTION CAST TURBO MANIFOLD - K26 FLANGE

The Wagner Tuning Audi RS2 Evolution Exhaust Manifolds are a high performance redesign of the original RS2 factory manifolds.The original OEM design reduced the exhaust gas flow to a power robbing 22mm inside diameter! Our engineers have removed the OEM bottlenecks and increased the flow rating providing a continuous 38mm unrestricted path from the motor to the Turbocharger.This results in increased throttle response, quicker turbo spool-up, and higher top end power capabilities. Each manifold is constructed of the same OEM casting material as the original RS2 manifolds (EN-GJSA-XNiSiCr35-5-2 letter: D5S), and is also cast in the same factory as the original manifolds to guarantee OEM+ quality! Each manifold is a performance work of art.OEM+ Fit and finish for easy installation The Wagner Tuning S2/RS2 Turbo Exhaust manifold features:     * Cast from High Grade OEM RS2 materials - EN-GJSA-XNiSiCr35-5-2 letter: D5S     * High-flow, pulse optimized for great throttle response & high power     * Designed for the “K26” style turbo flange mounting     * Additional 5mm compressor housing area allows for larger aftermarket Turbocharger mounting     * OEM Direct Replacement
