This manifold is a perfect example of engineering, combined with experience and commitment to this unique motor. Cast with a high nickel content for proper thermal dynamics, this manifold has realized HP figures of 500+ on current turbo kits.
The divided chambers within the exhaust manifold are a critical part of the design, maintaining the integrity of the independent Oxygen Sensor readings (One O2 sensor manages two hot rear cylinders and one cool front cylinder, while the other O2 sensor manages two cool front cylinders and one hot rear cylinder). These cylinder separations allow the Oxygen Sensors to deliver the correct fuel trims to the ECU.
