Best Automotive Performance Exhaust Manifolds in 2022

Last update: December 5, 2022

Are exhaust manifolds better than headers?

There is a lot of debate on which is better, headers or exhaust manifolds. Each have their own pros and cons, so it really depends on what you are looking for in a performance part. Exhaust manifolds are typically less expensive than headers, and they are easier to install. Headers usually provide better airflow and therefore better performance, but they can be more difficult to install. So, which is better for you? It really depends on your budget and your level of expertise when it comes to installation. If you are looking for the best performance,

Are long tube or shorty headers better?

There are a few schools of thought when it comes to headers. Some say that long tube headers are the way to go because they offer more power. Others believe that shorty headers are a better option because they're lighter and easier to install. Ultimately, it comes down to personal preference. Some people swear by long tube headers, while others find shorty headers to be the better option. There really is no right or wrong answer, so it's up to the individual to decide which type of header is best for their needs.

Are stainless steel manifolds better?

If you're looking for a high-quality, durable exhaust manifold, you can't go wrong with stainless steel. Stainless steel exhaust manifolds are more expensive than their cast iron counterparts, but they're worth the investment. Stainless steel is more resistant to corrosion and will last longer, even in the most extreme conditions.

Do cherry bombs add horsepower?

Cherry bombs are a type of firework that is often used to add a bit of flair to a Fourth of July celebration. While they may look impressive, there is no evidence that cherry bombs actually add horsepower to a vehicle. In fact, cherry bombs are illegal in many states because they can be dangerous if used improperly. If you're looking to add a bit of power to your car, there are much better and safer ways to do it.


Dorman 674-987 Driver Side Exhaust Manifold for Select Ford Models Review:


Cheap as chips and fits perfectly



Hooker 8501 Exhaust Manifold Review:


These fit perfectly and significantly reduced engine noise. The flange's additional material and rigidity enable the gasket to function as it should. The starter and various fluid lines were experiencing heat issues because of a pair of lengthy headers that just sat too low beneath the car and required several modifications to clear other parts. These are perfectly comfortable and functional. The vehicle being used is a second-generation Camaro with an LS1. Since I couldn't weld steel to stainless since the outlet flanges are made of stainless steel, I had to construct a steel version to attach to my exhaust. Although they are a little difficult to locate—I could only buy them online—the doughnut gaskets work excellent as a seal.



Crown Automotive 4883385K Exhaust Manifold Review:


Since I haven't yet placed it on my vehicle, I can just give it a construction rating. The flange is accurate and attractively thick, and it looks terrific. The welds appear solid. I'll update my evaluation once it warms up and I have a chance to install it.I can provide an update on fitment and how the installation went now that it has been completed. Even though I'm a somewhat skilled mechanic, this was one of the trickier wrenching tasks I've attempted. On the manifold, the lower four bolts are essentially inaccessible. To put them on, I needed a mirror, a lamp, and four "wobbly" extensions on a socket that I had to hold in my teeth. It took all of the afternoon to start and secure these four bolts. The gasket that came with the manifold appeared to be of lower quality, so I also purchased a better gasket. You must take special care to ensure that the manifold is securely fastened to the engine block's dowels; otherwise, you will have to disassemble it and start over. The manifold fits perfectly and without any problems.



BD Diesel Performance 1045985 Exhaust Manifold Review:


Easy to install, quick shipping. Would purchase again (at the cost, thank goodness I only needed one). Even so, the price was reasonable here. My standard manifold lost two bolts and warped, so I had to replace it. Upgrade to this BD if you need to replace your stock manifold by spending a little extra money. Though I suppose you can't win them all, it would be wonderful if it came with the gasket set.



Pacesetter 754110 Direct-Fit Manifold with Catalytic Converter Review:


So far, so good; there were no problems during installation. The quality seems to be good, and performance enhancements will be watched throughout the coming fill-ups. In addition, I changed the rear cat with a Pacesetter cat after experiencing some troubles with the previous model. Overall, I believe the engine is breathing better. Next, a new cat-back is put on.



Pacesetter 753022 OEM Replacement Manifold Converter Review:


I love these on my 2004 Xterra! You can definitely tell a difference when using these instead of the stock exhaust manifolds.



Pacesetter 754106 Direct-Fit Manifold with Catalytic Converter Review:


Your text will be rewritten by QuillBot. Start by typing or pasting something into this box, then hit the enter key.



Pacesetter 753021 OEM Replacement Manifold Converter Review:


It took some finagling to get it to line up with the stud holes in the block, but the performance seems fine, and it's far less expensive than OEM or other aftermarket solutions.


Do exhaust manifolds add horsepower?

Exhaust manifolds are one of the most important engine components. They play a vital role in the engine’s performance, and can add horsepower. The exhaust manifold’s job is to collect the exhaust gases from the cylinders and direct them into the exhaust system. A well-designed exhaust manifold will flow the gases smoothly and evenly, without any restrictions. This allows the engine to breathe more freely, and can add horsepower. There are many aftermarket exhaust manifolds available that claim to add horsepower. But it’s important to do your research and make

Do headers sound better than manifolds?

There are a few key reasons why headers tend to sound better than manifolds on performance vehicles. For one, headers provide a more direct path for exhaust gases to flow from the cylinders to the exhaust system. This can lead to increased power and a more aggressive sound. Additionally, headers typically have larger diameter tubing than manifolds, which also contributes to increased power and a more aggressive sound. Finally, headers are often made from lighter weight materials than manifolds, which can further contribute to increased power.

Does stainless steel exhaust increase power?

Stainless steel exhaust systems do not increase power, but they may improve exhaust flow and, as a result, slightly improve power.

How much horsepower does a performance exhaust add?

A performance exhaust can add up to 5 additional horsepower to your car. This can be a significant increase, depending on the make and model of your vehicle. The main benefit of a performance exhaust is the increased airflow it allows. This can lead to better combustion and more power. In addition, a performance exhaust can also improve your car's fuel economy.

How much horsepower does removing a catalytic converter add?

A catalytic converter is a device used to convert harmful exhaust gases from an internal combustion engine into less harmful gases before they are released into the atmosphere. Removing a catalytic converter can add horsepower to a car because it reduces the back pressure in the exhaust system. This, in turn, allows the engine to breathe easier and make more power. In addition, removing the converter can also lighten the load on the engine, which can also add horsepower.

How much HP do camshafts add?

How much HP do camshafts add? There is no definitive answer to this question as it depends on a number of factors, such as the type of camshaft, the engine it is being fitted to, and the other modifications that have been made to the engine. Generally speaking, however, a camshaft upgrade can add anywhere from 5 to 20 HP to an engine.
