The Gruppe-S manifold is a 4 to 1 unequal length manifold. It will retain your boxer rumble and features T304 Stainless Steel piping, mandrel bends, and CNC precision cut flanges. The 4-1 collector is cast to ensure the smoothest possible low rates. This header is dyno proven to make power; it will not lose power or torque in 2.5L applications anywhere in the RPM range. 2.0L or 2.5L motors will lose some low-end and mid- range power to gain more high-end power and torque. The more modified your vehicle is, the more pronounced the gains from these headers will be.
