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 PDI 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.

• Hello heres a great PDI manifold that will reduce back pressure and make your motor have more power and run cooler!!!
• The one and only big rig performance manifold on the market!!!!
• performance Diesel Inc has forged new exhaust manifolds of High Molysilliconductile material used to cast turbo housings. Allowing both the manifold and turbo housings to cool at similar rates,reducing the risk of warping and cracking to the manifold in key locations.Each manifold is designed with a ball seal at each joint eliminating exhaust leaks, while allowing the metal to expand as the manifold heats up. With an increase in airflow and decrease in exhaust gas temperatures the overall performance of your truck will be improved,showing more horsepower and torque.
• Also as an added benefit Performance Diesel Inc. Is replacing all stock bolts used to hold the turbo to the manifold with quality studs to prevent bolt breakage, caused by stress and heat.
