There is no definitive answer to this question as it can vary depending on the vehicle and driving conditions. However, some people believe that long tube headers can help increase fuel efficiency by improving engine airflow and exhaust scavenging. Ultimately, it is up to the individual to decide if the potential benefits are worth the cost of upgrading to long tube headers.
Long tube headers are one of the most popular modifications for performance cars. But do they actually improve fuel economy?
The answer is a bit complicated.
In theory, long tube headers should improve fuel economy because they allow the engine to breathe better. This means that the engine doesn’t have to work as hard to produce power, which should result in better fuel efficiency.
However, there are a few factors that can offset this potential gain in fuel economy.
First, long tube headers usually add weight to the car, which can decrease mileage slightly. Second, they often require larger diameter tires, which also decreases mileage. Finally, long tube headers can sometimes cause the engine to run hotter, which can lead to higher fuel consumption.
So while long tube headers may theoretically improve fuel economy, it’s not always the case in practice. If you’re looking for ways to increase your car’s mileage, there are other modifications that may be more effective than long tube headers.
Do Headers Increase Horsepower
Yes, headers can potentially increase horsepower. This is because they allow exhaust gases to flow more freely from the cylinders, which can improve engine efficiency. In some cases, this can lead to a small power gain that may be noticeable on the track or dyno.
However, it’s important to note that not all engines will see a benefit from headers – some may actually lose power due to inefficient scavenging of exhaust gases. Ultimately, it’s up to the individual tuner to determine whether headers will provide any benefits for a particular engine setup.

Do Headers Improve Gas Mileage?
headers will not improve your gas mileage. In fact, they may actually decrease fuel economy because of the increased drag from the taller, larger shape.
What are the Benefits of Long Tube Headers?
There are a few benefits to upgrading your vehicle’s exhaust system with long tube headers. First, they tend to create more horsepower than stock headers. This is due in part to their design, which allows for better scavenging of exhaust gases.
Additionally, long tube headers typically lead to improved fuel economy as well as increased torque. Finally, they often give the engine a deeper, throatier sound that many gearheads find appealing.
How Much Hp Does Long Tube Headers Add?
If you’re looking to add a little extra horsepower to your car, long tube headers are a great option. But how much horsepower do they actually add? Let’s take a look.
Long tube headers are one of the most effective ways to increase horsepower in your car. They work by increasing the amount of exhaust gas that can flow through the engine, which allows more air and fuel to be burned and thus creates more power.
Depending on the size of your engine and other factors, long tube headers can add anywhere from 10-50 horsepower.
So if you’re looking for a significant power boost, they’re definitely worth considering. Just keep in mind that they will also make your car louder, so if you’re not into that sort of thing, they might not be the best choice for you.
Do Long Tube Headers Make a Difference?
If you’re looking to improve your car’s performance, one of the first things you might do is upgrade the headers. But what are headers and do they really make a difference? Let’s take a look.
Headers are basically exhaust pipes that are designed to increase airflow out of the engine. They often have larger diameters than stock exhaust pipes and they may be tuned to specific engine frequencies in order to further enhance performance. In some cases, headers can also be slightly longer than stock exhaust pipes.
So, do headers make a difference? The answer is yes, but it depends on what kind of difference you’re looking for. For example, if you’re just looking for a slight improvement in horsepower and torque, then long tube headers might not be worth the investment because they can be quite expensive.
On the other hand, if you’re aiming for significant gains in power, then long tube headers could be exactly what you need.
Of course, there are other factors to consider as well when choosing header upgrades. For example, your car’s overall weight and gearing will play a role in how much of an improvement you’ll see from header upgrades.
But in general, if you’re looking for more power, better fuel economy, or even just a deeper sound from your exhaust system, then upgrading to long tube headers is definitely something to consider.

Conclusion
If you’re looking for a way to improve your car’s fuel economy, you may be wondering if long tube headers can help. While they can’t exactly hurt, the truth is that there’s no evidence to suggest that they actually make a difference in terms of mpg. So, if you’re considering spending the money on them, you may want to think twice.
