Forged from HSM material, This manifold eliminates the warping and cracking problems of an OEM manifold. With a high moly content, the worry of center-divider failure and metal dissipation is eliminated. Each manifold is designed with a full-contact joint, which allows for heat and expansion, while holding a tight, efficient seal. Each manifold includes high strength, quality studs for added strength and durability. Improved air flow helps to lower exhaust temperatures, reduce turbo lag, and increase horsepower and torque.
