PDI Big Boss CAT 3406E/C15/C16 Exhaust Manifold

PDI Big Boss CAT 3406E/C15/C16 Exhaust Manifold

Available for:  Caterpillar 1994-2004 3406E, C15, C16 Engines

Key Benefits

• 20% increase in airflow over stock
• 75-100 degree cooling of EGTs
• High Silicon with Molybdenum Ductile Iron (HSMD) that eliminates weak points such as warping, cracking, and center divider failure from heat erosion. This material, combined with a redesign of the mounting surfaces, eliminates common failures due to a fatigued manifold.

PDI exhaust manifolds have been designed to maximize the exhaust air flow to reduce turbo lag time and cool exhaust temperatures. In the design of the manifold each port is analyzed and tested to provide a balanced flow to the turbocharger. Big Boss Exhaust Manifolds produce, on average, a 20% air flow increase over a stock manifold, cooling exhaust temperatures by 75-100 degrees. PDI manifolds are a big part in maintaining the best exhaust pressure to boost pressure ratios which will provide potential for increased fuel economy.

A simple upgrade for your CAT engine! Fits most engines with serial number prefixes 5EK, 6TS, 1LW, 1MM, 6NZ, 7CZ, and MBN.
