Are ATP Exhaust Manifolds Good? (Explained For Beginners)

As a car owner, you know your car needs maintenance from time to time. One such area of maintenance is the exhaust system when there comes a time you need a new replacement exhaust manifold.

One of the replacement exhaust manifolds you can get is the ATP exhaust Manifold manufactured by ATP Automotive.

But are the ATP Exhaust Manifolds any good?

Let’s Find Out if ATP Exhaust Manifolds Are Any Good

ATP exhaust manifolds are considered by many to be some of the best on the market. This, of course, is a matter of preference, but there are some features of ATP exhaust manifolds that qualify them as high-end products that are the choice of many car owners and mechanics.

ATP manifolds are aftermarket manifolds. They do not come stock on vehicles, but they are often chosen as the best replacement option whenever a new manifold is needed or if a vehicle owner just wants to improve their vehicle’s performance.

They are somewhat expensive compared to other brands, but since they come with a lifetime warranty and are made of some of the best quality materials, they are considered by those who use them to be well worth the cost.


What Are ATP Exhaust Manifolds And How Are They Different From Regular Ones?

High-quality OE replacement exhaust manifolds are available from ATP Automotive Graywerks. In order to ensure that each manifold will install and perform as intended, they are all built according to the original part specifications of the vehicle they are designed for.

Gray-iron and ductile steel are used in this design, as well as more advanced stainless steel and cast iron steel types.

A machine-finished flange ensures perfect flatness, even mounting, and no leaking. The manifolds feature ATP limited lifetime warranties as well as heat shields and plugs if needed for the right vehicle. They include upper and lower gaskets as well as lower flange hardware.

Manifolds manufactured by these brands are distinguished by their materials. They perform better and are more efficient because of the high quality of materials.

Additionally, it prevents the mounts from falling off the vehicle or coming loose, so they are more secure on vehicles. 

The Lifetime warranty also adds to the value of the manifold and gives driver’s some extra peace of mind.

What Are The Types Of ATP Exhaust Manifolds?

Many different types of vehicles are served by ATP exhaust manifolds. They can design almost all vehicle exhaust manifolds on the market.

Every design is specific to the type of vehicle it is designed for, and each part number corresponds to that vehicle.

Depending on the shape, size, and material of the vehicle’s engine, they are ideal for it. Stainless steel manifolds and cast iron manifolds are also available. Each has its own advantages and disadvantages.

Stainless Steel

An exhaust manifold is a diverging manifold that connects to the engine cylinder block and tunnels the gases out to the exhaust muffler and catalytic converter via the exhaust pipe.

In order for it to operate efficiently, the exhaust resistance must be minimized and mutual interference between cylinders must be avoided. In the case of exhaust gas concentration that is excessively concentrated between cylinders, the exhaust gas from one cylinder will simply hit that from the other cylinder when it is exhausted.

By doing so, the exhaust gas resistance increases, lowering the engine’s power output. To solve this problem, the multiple exhaust pipes of each cylinder must be separated as much as possible, and each branch must be made as long as possible so that the gas mixture between manifolds is reduced as much as possible.

Stainless steel exhaust manifolds are used by some racing cars to reduce exhaust resistance.

In addition to its thick wall thickness, cast iron exhaust manifolds are quite heavy and cannot increase engine performance. Stainless steel exhaust manifolds have a wax casting and can produce thinner walls to make them lighter.

Furthermore, the surface quality and dimensional accuracy of stainless steel exhaust manifolds are far superior to those of cast iron. All of these advantages contribute to better engine performance when using cast stainless steel exhaust manifolds.

Cast stainless steel exhaust manifolds have the advantage of being extremely durable and robust over cast stainless iron exhaust manifolds, which it can be used in extreme hot or cold conditions.

Cast stainless steel exhaust manifolds are highly reliable and can last for many years when purchased by a company. The fact that stainless steel exhaust manifolds are durable and long-lasting makes them a very good investment.

Rust and corrosion are not a problem for cast stainless steel exhaust manifolds. In automotive industry settings where rust and corrosion are common conditions, stainless steel exhaust manifolds are a perfect choice.

Also, cast stainless steel exhaust manifolds are stronger, more durable, and more resistant to high pressure than cast iron exhaust.

Cast Iron

Joints and gaskets are part of a cast iron manifold’s construction. In a worst-case scenario, the manifold could collapse under the pressure of heat, resulting in catastrophic engine failure.

When the parts expand and contract with heat, the sealing around the gaskets may gradually deteriorate and the gaskets may leak, cause corrosion, or both. Manifolds are made of cast iron, so why is it used? As a result, manufacturers are able to keep their costs down while using this material.

There can be up to 1/4 inch of scale left on cast iron after it corrodes in a blistering fashion. Overheating or blockage of water flow can result in a thick scale, which further accelerates corrosion. A rusted internal wall can deteriorate irreversibly if left to rust for a long period of time.

Cast iron manifolds don’t have an expiration date, and internal damage often goes undetected for a long time.

Every few years, cast iron manifolds need to be completely replaced after being periodically removed and inspected for corrosion. If there are any signs of corrosion, the manifold should be replaced as there is a chance it may break or fall or come loose from the vehicle.

A cast iron manifold can weigh upwards of 100 pounds because of its thick walls that slow down corrosion. As a result, the boat loses power, performance, and fuel efficiency due to the added dead weight.

Every time the manifolds need removing or replacing, two people must help haul them out of the engine bay because of their weight.

What Are ATP Exhaust Manifolds Made Up Of?

ATP exhaust manifolds are made of either stainless steel or cast iron.

The exact material used to make each manifold depends on the part number or the vehicle it is made for.  Each material has its own benefits and works better for certain types of manifolds and certain types of vehicles. ATP always

How Long Does The ATP Exhaust Manifold Last?

Most exhaust manifolds are capable of lasting for over 100,000 miles.

ATP exhaust manifolds are made out of some of the best quality materials and therefore, will last up to 200,000 miles.

One of the biggest appeals of an ATP exhaust manifold is the lifetime warranty. If something were to happen to the manifold, the warranty would cover repairs and replacements. This means your manifold could potentially last for as long as you own the vehicle.

Final Thoughts

If you are planning to get an aftermarket exhaust manifold or if your original exhaust manifold breaks and needs to be replaced you may want to consider getting an ATP exhaust manifold from ATP Automotive.

This type of manifold is deemed to be one of the best on the market because of its high-quality materials and the inclusion of a lifetime warranty.
