What Do Aftermarket Headers Do

Headers are one of the easiest bolt-on accessories you can use to improve an engine’s performance. The goal of headers is to make it easier for the engine to push exhaust gases out of the cylinders. The gasoline in the cylinder burns and expands during this stroke, generating power.

Do headers add horsepower?

In general, a quality set of headers should provide an increase of approximately 10-20 horsepower, and if you’re restrained with your right foot, you may even see an increase in fuel mileage.

What are the benefits of aftermarket headers?

While it may not make a drastic difference such as installing a turbo or supercharger, investing in high-performance headers can increase the engine’s torque, and subsequently the car’s horsepower. Depending on the type of car you have and exhaust system, upgrading the headers can result in a 5% increase in horsepower.

Do aftermarket headers increase sound?

But will it improve the sound of your car?! To put it simply – yes, an exhaust header will slightly improve the sound of your car. Exhaust headers are wider and thinner when compared the stock system. These characteristics allow the sound vibrations to flow better and exit the car – allowing for a louder sound.

Do headers make a car go faster?

However, headers alone won’t make your car much faster. You might pick up 2–4% more horsepower. Headers are a modification that is typically done to support other mods such as more aggressive cams, air intake, and engine tuning.

Is a tune needed for headers?

And for aftermarket headers, the answer is yes, you should tune your car when installing a new exhaust header. Major performance mods like a header can significantly alter important variables like air/fuel ratio. Tune is required to ensure you get the most out of the header without future problems.

Can headers damage engine?

Is It Bad To Run A Motor Without Headers? As the engine burns, the valves are heated. In a manifold or header, cool air may be pulled back into the heads, causing cool spots on the valves, which could cause them to burn or break.

Do headers make a car louder?

Car headers do not make your car louder as compared to the stock exhaust manifold. This aftermarket addition is used to improve the performance of your car and give you a cleaner-sounding exhaust. The actual volume of the exhaust won’t change.

Does aftermarket exhaust affect engine?

In some cases you will notice a power gain, but that isn’t always the case. The free flow of exhaust out of the back of the car can make your engine run smoother as well. If you use your car on the track, the aftermarket exhaust can reduce weight.

How much torque do headers add?

We did the math and came up with a staggering average increase of 46 lb-ft of torque. That means that throughout the entire 4,000-rpm band from 2,600 to 6,600 rpm, the engine made 46 lb-ft of torque more with the headers at every single data point.

Whats louder short or long headers?

As for drawbacks? Shorty headers aren’t as loud as long tube headers, although they’ll definitely have better sound than your stock manifold. You can choose unequal length headers for better sound, but equal length is the way to go for consistent gains in performance.

Do headers improve performance?

Is a cherry bomb a muffler or resonator?

Uh a Cherry Bomb is a resonator if it’s spliced in upstream of the rear muff.

What is better headers or exhaust manifold?

Why are headers are a better choice than an exhaust manifold? As stated above, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure.

Do headers increase mpg?

Exhaust headers are lighter. It is proven that exhaust headers which are tuned for economy, can improve the gas mileage by a small margin. And this is around 2-3 mpg improvement on the highway or city. This isn’t significant compared to the performance they deliver.

How much do headers cost?

The price of a header depends on how many cylinders your engine has, the type of finish you want, as well as the brand. We offer headers that cost around $200 all the way up through performance headers with price tags above $1,000. There’s a solution for every engine performance enthusiast and every budget.

Is open headers the same as straight pipe?

Open headers is where you run your car without any exhaust pipe, CATs, or mufflers. Cars with open headers let exhaust gases out from its headers – no additional piping, mufflers or CATs involved.

Does header void warranty?

Short Answer: YES. Long Answer: Any modification has the potential to void your warranty, but it is on the dealer to show/prove that the modification you did caused the failure to your car (ie powertrain, exhaust, electrical).

How much is a tune?

A standard tune up can cost $50 to $200, while more complex tasks can range from $500 to $900. This is taking into consideration the price of the parts and labor required to perform the work. If you are able to properly service an automobile, you can save yourself a lot of money.

What type of headers should I get?

Full-length headers help produce more overall power with good power in the low- and mid-rpm ranges—right where most street-driven vehicles can use it the most! The longer primaries also reduce the chance of escaping gases getting drawn back into another pipe.

Are headers hard to install?

The fact is, today it’s usually cheaper to run headers than the stock manifolds! But nobody wants to hack their Mopar’s fenderwells, or worry about bottoming out and mangling the headers, or constantly fix leaks. Plus, headers are notoriously difficult to install, especially on Mopars.

Can you have headers and a catalytic converter?

It would be illegal. If however, you live somewhere that doesn’t care about the cats all you would have to do is get a pipe the same size as the exhaust and have it welded in place of the cat. The car will run better and get better mileage but there will be a check engine light on in the dash.
