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. They are constructed of individual tubes (one for each exhaust port) that meet in a larger tube called a collector.

Where do headers mount?
Most headers are designed to be installed from the bottom of the vehicle. Furthermore, your car or truck will likely need to be lifted at least 18 inches off the ground to get the proper installation angle.
How do you insert a header?

- Go to Insert > Header or Footer.
- Choose from a list of standard headers or footers, go to the list of Header or Footer options, and select the header or footer that you want.
- When you’re done, select Close Header and Footer or press Esc.
Do headers make your 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.
Do headers replace exhaust manifold?
Long tube headers build a lot of power in the mid to high rpm range. It varies from car to car, but generally they replace your OEM exhaust manifold, a downpipe and catalytic converter.
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.
What do new 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.In a normal engine, once the exhaust gases exit the cylinder they end up in the exhaust manifold.
Are headers illegal?
Headers aren’t always illegal, some vehicles come stock with them and most short tube headers are considered legal in most states.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 does it cost to install headers?
I think $500-600 is average, with $800 being too high. However, I also had quotes for 1k at some of the bigger, nicer speed shops. It should be a 6-8 hour job for a decent shop. If you can get a good shop to do it for $400, then definitely pay the man…
How much HP 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.
What type of headers are best?
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.
What headers are better short or long?
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.
Which is better manifold or headers?
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 change car 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.
Are downpipes and headers the same thing?
Re: Difference between Downpipes and Headers (DaPeaz)
Yes, but they are only marginally better than the dual outlet manifold and down pipe configuration. That is correct. Headers eliminate the exhaust manifold and the down pipe. Some headers also eliminate the catalytic converter.
Do you need a tune 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.
How much horsepower do headers add to a 350?
There was an immediate increase of 16 horsepower and a more dramatic increase of 53 foot-pounds of Torque after Chevy High Performance Magazine installed a set of Hooker heads on a stock engine.
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.
Why are headers so expensive?
Kooks headers are made of 304 stainless, which is way more expensive than plain steel. They also are TIG welded. This is very important because TIG welding while stronger is very expensive. On average, TIG welding takes 3x as long as MIG welding which makes production slower.
Do headers delete the cats?
and yes it would be. your race header would delete the cat and your exhaust would bolt right up to your race header.
