The goal of headers is to make it easier for your engine to push exhaust gases out of the cylinders.
It works by eliminating the manifold’s back pressure.
Instead of sharing a common manifold, each cylinder gets its own exhaust pipe.
Therefore, you notice more power and torque from your engine.

Do headers increase horsepower?
This makes aftermarket exhaust headers a good place to find extra horsepower and increase torque. Exhaust headers work by making it easier for exhaust to flow out of an engine’s cylinders. But long-tube headers do the best job of building torque and horsepower from mid-range to top-end RPMs.
Are headers legal?
Most of the headers are 50-state street legal, which means that they don’t interfere with pollution-controls on your vehicle. Some headers are designed for off-road or racing vehicles that are exempt from smog certification, so they are not street-legal.
Do headers make your car faster?
Changing your headers to a free flowing set of pipes allows the engine to produce more power by improving the scavenging of waste gasses from the cylinders. However, headers alone won’t make your car much faster. You might pick up 2–4% more horsepower.
Are headers worth the money?
Are Headers Worth The Performance Improvement? The answer is yes, headers will boost performance – IF your vehicle is “prepared” for them. Headers take the place of your exhaust manifolds, which are the first part of your exhaust system between the cylinder heads and the front exhaust pipes.
Do headers make a car louder?
Yes they will make it a little louder, but not a significant amount. The tone will change and it will sound much more “tinny”. If you leave your stock mufflers you will not have a problem, but if you do a cat-back it may get too loud for you.
How much horsepower do headers add to a 350?
Chevy High Performance Magazine installed a set of Hooker headers onto a stock engine and saw an immediate increase of 16 horsepower and a more dramatic increase of 53 foot-pounds of torque. Headers bolt onto the block and attach to the stock exhaust pipes and catalytic converter.
Do shorty headers add horsepower?
For all-out power, the long-tubes win, but in many installations the shorty headers are a much easier fit. The larger pipes showed a healthy increase in top end power of 21 peak horsepower, while even managing a torque advantage right from the bottom of our test range of 3,000 rpm.
Do headers make a difference?
An aftermarket stock header deals with the exhaust gasses in a much more efficient way, which improves the overall performance of your engine. Performance headers are more concerned with increasing performance rather than reducing the noise from the engine.
Will straight pipes hurt my engine?
Putting straight pipes on your truck, or decreasing your “back pressure” will not hurt your engine or performance. Below the answer is fully explained.
Do headers increase mpg?
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 headers CARB legal?
A: Street headers are direct replacements for the OEM factory and are usually CARB approved or CARB pending. Please check with us or an authorized dealer to make sure your specific application is CARB Legal. A: Race headers are for off road use only and are not street legal. Our race headers are not street legal.
