Do headers add horsepower?
Remember, headers increase horsepower a lot more on a modified engine. If you have enough room to spare for a long tube header, do so. That'll produce quite a lot of extra horsepower over stock exhaust manifolds.
What are headers good for?

What is the purpose of headers on an engine?
The purpose of a car header is to eliminate back pressure which is created in the manifold. Instead of a single pipe shared by all of the cylinders, each cylinder has its own exhaust pipe which connects to form a bigger pipe known as the collector. The individual pipes are bent so that they are of the same length.
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.
How much HP does exhaust add?
Everything that comes before the muffler, where the pressure is greatest and performance potential is highest, will remain tight and congested. MagnaFlow, an aftermarket exhaust manufacturer, says that its customers can expect horsepower gains of around 10 percent (which is a pretty commonly-quoted figure).
Do headers help gas mileage?
While more involved from an installation standpoint, headers in combination with a cat-back system will give you a measurable boost in power. In most cases, fuel mileage will remain the same or improve a bit.
Are aftermarket headers illegal?
Headers aren't illegal, however, long tube headers on the other hand are a bit of a different story. Not only will they make your vehicle louder, but it is also considered tampering with your vehicles emissions, which according to the EPA is illegal under federal law.

How much performance do headers add?
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.
Do headers increase torque?
Improving your exhaust headers and using wider valves can help you with ventilating the cylinder more completely, allowing more air and fuel to come in during the next cycle. This improves the performance and torque of the vehicle. Torque is all about air intake and fuel combustion inside the cylinders of the engine.
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.

1. Why this guide exists
This guide exists for naive clients arguing with their devs over silly pages scores and “security tests”.
2. How do Security Headers work?
Before we even talk about security headers, you must understand that they’re simply HTTP headers and to know what HTTP headers do. (Yes, do read that fucken guide or you’ll be completely lost for this guide.)
3. Real-world examples of security headers (and my opinions)
Here’s more or less how I feel about each one of them (and WHY). Of course…you’re welcome to do whatever you want, and go against my recommendations. I’m not here to argue. But please, don’t be a PITA client to your dev.
