Description
PDI designed their exhaust manifolds 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.
Features
- 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.
- Made in the USA
