Forged from HSM material, PDI’s manifolds eliminate 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 ball seal joint, which allows for heat and flex at the joints, while holding a tight, efficient seal, includes high strength, quality A280 Inconel Studs for added strength and durability. Improved air flow helps to lower exhaust temperatures, reduce turbo lag, and increase horsepower and torque.
