About the PDI Exhaust Manifold

Performance Diesel Inc. (PDI) Exhaust Manifolds 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 approximately a 20% airflow increase over a stock manifold, which results in cooling exhaust temperatures by 75-100 degrees. PDI manifolds help maintain the exhaust pressure for the optimal boost pressure ratios. Consistent boost provides the potential for increased fuel economy.

PDI uses only the best material for the Big Boss Exhaust Manifolds. Each PDI exhaust manifold is built from a superior grade of 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.

Benefits of Ceramic Coating. 

Ceramic coatings make exhaust manifolds look great, but there are more benefits to having this treatment done on your PDI exhaust manifold than just aesthetic appeal.

Rust protection

In a process similar to powder coating, applying a ceramic coating to your PDI exhaust manifold bonds the ceramic molecules to the outer and inner surfaces of the manifold. This ceramic coating is rust-resistant and will keep your manifold from corrosion as long as the ceramic coating stays intact, and no previous corrosion is trapped underneath. Diesel exhaust often contains corrosive particles, but these won’t be able to hurt your PDI exhaust manifold since it has a good ceramic coating to protect it.

Heat resistance and insulation


The second reason why having a ceramic coating is beneficial is that it will help keep the heat where it should be. A common problem of untreated manifolds is that they tend to leak heat. This can be dangerous because it causes excessive heat under the hood and other areas which exposes materials like plastics and softer metals to conditions that they are meant to hold up in.

Another reason why leaking heat is a problem is that there are components of your diesel engine that require a certain threshold of heat to properly function. If the heat is allowed to leak away, areas like your catalytic converter and your exhaust system won't have the heat they need to operate properly.

A ceramic coating helps keep the heated exhaust air where it should be, namely traveling through the engine along its proper channels on its way to the exhaust. It also insulates your pipes against the heat, protecting them from warping, cracking, and even discoloration.

Each PDI Exhaust manifold comes pre-coated with either a black or polished ceramic to help ensure a long product life.

Slip Joint Design


Your engine gets very hot when it is in use, and the high temperatures have been known to cause OEM manifolds to warp and crack, causing manifold leaks. The warping and cracking come from the natural expansion and contraction in the metal manifold due to the extreme changes in temperature that happen regularly while the engine is running. Ceramic coatings on each PDI exhaust manifold help protect them from the heat, but PDI didn’t stop there. They went and made their exhaust manifold adaptable. 

OEM manifolds, especially those for older engines, almost always come in one single piece. Your manifold can experience different levels of heat in different parts of it at the same time, and for single-piece manifolds that can cause warping and cracking. The PDI exhaust manifold design combats this issue by having multiple segments that are connected with slip joints. The slip joints allow the different parts to expand and contract independently of each other, and have a little bit of room to move. This design protects the integrity of the manifold, preventing cracks and warps. This means less chance of leaking, which increases the life of the manifold, as well as the rest of the engine. 

Why Your Manifold Is Important For Your Turbo

Your turbo connects directly to your exhaust manifold and relies on the manifold to provide it with sufficient exhaust to spool. Thanks to its superior design and special ceramic coating a PDI exhaust manifold can maintain a constant exhaust pressure as it travels from the engine through the manifold and into the turbo. Having this consistent pressure is key because it enables your turbo to build up pressure for dependable boosting. If the pressure is lost or leaked away before it can get to your turbo then your turbocharger will be unable to provide the reliable boost that your engine needs. 

The boost from your turbo is a key factor in the gains in horsepower, torque, and gas mileage that every trucker is looking for. Exchanging your OEM exhaust manifold for a PDI exhaust manifold can make a world of difference for your vehicle, as it will channel the exhaust gasses to where they need to be, and keep the gasses and heat out of where they shouldn’t.
