Exhaust Manifold

We have 3,047 Items for Exhaust Manifold In-stock.

To effectively boost engine power and performance, install a highly efficient exhaust manifold to upgrade fuel efficiency. By enabling your vehicle to follow the course of your driving style with no fail, it unleashes its full potential on high performance applications delivering an unmatched driving experience you never knew your vehicle is capable of. This exhaust system component yields huge savings with longer life efficiency and consistently reliable service. When selecting your exhaust manifold replacement, strength and durability must be the determining factors to ensure powerful engine performance that lasts. The product is crafted from cast iron or tubular steel addressing the harshest working conditions with its durability and performance features. Mounted to the side of your engine cylinder head, it is sealed with exhaust manifold gasket to eliminate leaks and facilitates continuous free flow of fuel exhausts. It is designed to guide the exhaust gases out of the system and leave the cylinder heads relatively cool. Depending on your engine's exhaust system specifications, this engine component may also serve as a mounting location for air injection system hardware or oxygen sensor. Some exhaust manifolds designs employ a heat riser valve controlled by temperature sensitive spring that diverts hot exhaust gases through separate passages within the intake manifold. This system enables your engine to maintain ideal working conditions where components may work at their peak efficiency. Exhaust manifolds must be periodically checked to ensure that connections are tight, leak-free, and crack-free. A strange ticking noise when you accelerate may indicate that damages are starting to brew. Submit your vehicle to the expertise of a professional technician once you suspect problems with your exhaust system to eliminate the risks of failure. Quality and heavy duty factory equivalent to your stock exhaust manifolds are conveniently available for specific vehicle applications.

3 Critical Things to Consider When Buying an Exhaust Manifold

Exhaust manifolds are usually made from porous metals that expand and contract depending on the temperature. This makes them more prone to cracks over time. Once your car's exhaust manifold breaks, the engine's performance will be affected because of the unequal air-to-fuel ratio. Also, harmful exhaust gas will leak into the car's interior, putting yours and your passengers' health at risk. This is why a damaged exhaust manifold should be replaced immediately. If you're in the market for a replacement part, you should consider these three critical things so that you won't regret your purchase.

OEM or aftermarket?

OEM manifolds are typically made from cast iron, so they are inexpensive. But because of production cost constraints, some OEM manifolds are susceptible to rust and corrosion.Aftermarket manifolds, on the other hand, are engineered for optimum engine performance. They can be made from stainless steel, coated mild steel, or aluminized steel. However, aftermarket manifolds are more expensive than OEM.

Exhaust wrap, ceramic paint, or ceramic mixture?

Proper thermal insulation is essential to help prevent overheating inside your car's engine bay. Below is a list of the most common types of insulation used on an exhaust manifold.

  • Exhaust wrap: This type offers excellent insulation because it's wrapped completely around manifolds. Though it's relatively cheap, it can cause premature manifold degradation.
  • Ceramic paint: Usually sprayed or brushed onto manifolds, ceramic paint reduces the heat through radiation but not that much.
  • Ceramic mixture: Because of its very good thermal insulation, ceramic mixture is commonly used on performance cars and race cars.

Stainless steel, aluminized steel, or cast iron?

If you're having a hard time choosing the best type of exhaust manifold, here's a list of the advantages and disadvantages of the common types of manifold.

  • Stainless steel: This kind of exhaust manifold is rust resistant. It can also retain its chrome-like shine for a long time. However, despite these benefits, stainless steel manifolds are more expensive than other types.
  • Aluminized steel: By forming a layer of oxide, aluminized steel prevents corrosion. Although it's cheaper and lighter than stainless and cast iron, it easily rusts once the oxide layer is scratched or dented.
  • Cast Iron: Stock exhaust manifolds are made from cast iron, so they are affordable. However, they tend to be on the heavy side, and they don't boost engine performance that much.

Final Tip:

When picking the right part, always make sure that you will buy from a trustworthy brand. Remember that even though price affects quality, you shouldn't compromise durability or your budget.

DIY: Replacing a Damaged Exhaust Manifold

The exhaust manifold directs all the exhaust gases from the engine to the exhaust system. Without it, poisonous exhaust gases will reach your car's interior, and the car's engine will be damaged. If your car's exhaust manifold is damaged, you have to replace it immediately. This guide will show you how you can replace it without visiting a mechanic.

Difficulty level: Moderate

Tools Needed:

  • New exhaust manifold
  • Torque wrench
  • Socket wrench
  • Floor jack
  • Jack stands
  • Rubber mallet

Step 1. Park your car on a level surface. Then, lift up the front part using a floor jack. Don't forget to place jack stands under your car to make sure that it will hold up.

Step 2. Locate the exhaust manifold. It's usually attached at the engine and the exhaust piping.

Step 3. To remove the manifold from the exhaust piping, use your socket wrench to unscrew the bolts holding it in place. Then, remove the exhaust pipe from the manifold.

Step 4. Remove the bolts attaching the manifold to the engine with your socket wrench. Depending on your car's engine, the manifold may be secured by eight to 12 bolts.

Step 5. Gently tap the manifold to free it from the engine cylinders. Then, completely remove the exhaust manifold.

Step 6. Make sure that the new exhaust manifold, exhaust piping, gaskets, and cylinders are clean to install the new manifold properly.

Step 7. Attach the gasket on the new exhaust manifold. While making sure that the gasket is in place, slide the new manifold into the cylinders.

Step 8. With your torque wrench, screw the bolts attaching the new manifold to the cylinders.

Step 9. Attach the new manifold to the exhaust piping, and screw the bolts with the torque wrench. Your car now has a new exhaust manifold!
