PDI Big Boss exhaust manifolds are engineered to maximize exhaust airflow, reduce turbo lag, and lower exhaust temperatures. Each port is analyzed and tested to deliver balanced flow to the turbocharger — producing, on average, a 20% airflow increase over a stock manifold and cooling EGTs by 75–100°F. Maintaining the ideal exhaust-pressure-to-boost ratio provides the potential for improved fuel economy.
PDI uses a superior grade of High Silicon Molybdenum Ductile Iron (HSMD) that eliminates weak points such as warping, cracking, and center-divider failure from heat erosion. Combined with redesigned mounting surfaces, this eliminates the common failures of a fatigued manifold.
