PDI Big Boss Exhaust Manifolds are designed to maximize 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 up to 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.
