Headers are installed because they boost the rate of exhaust flow out of your engine compared to OEM stock exhaust manifolds, which are typically designed to take up as little space as possible. ... There's no benefit to putting headers on if the exhaust flow is only going to be choked further down the line.

In addition to, how much are headers for a truck?
Headers can cost anywhere from $130 to $2,392, depending on the design, finish, and hardware included.
From everywhere, do headers make a truck louder? Like other modifications, headers speed up the flow of your exhaust. Plus they take away some noise insulation, although not as much as some modifications. Usually, headers have collectors or tubes that are larger in diameter than the stock setup, which also contributes to the increased sound.
Ever, do headers make a difference in sound?
Yes headers do change the exhaust tone especially under throttle. I think the tone tends to be deeper. You will also hear a difference because of the material used in the header vs cast iron manifolds. Cast iron manifolds tend to quiet down the exhaust while headers tend to have a mild ringing to them.
Can headers damage engine?
Headers will not hurt your engine.

Adding headers simply brings that part of the system up to par with the rest of the parts. 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.
The average set of headers cost between $1500 and $2000 depending on the car and size of tubing and other options that are available. Ceramic coating is available and encouraged, but does cost extra.
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.

There are 2 primary ways to make your truck louder. One way is to upgrade your factory exhaust system to an aftermarket unit that allows more free flow of exhaust fumes. You can also make your truck louder by upgrading the air intake system to a larger, less restrictive performance intake unit.
Unequal length headers offer a deeper rumbling sound and a little more low-end torque, but equal length headers offer greater performance gains consistently.
Another disadvantage of headers is that, due to their thinner walls, they do not absorb as much sound as cast iron exhaust manifolds, making them louder (although some may see this an advantage).
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. Two other components that affect performance and mileage are the oxygen sensor and the catalytic converter.
It'll be louder than stock, but not obnoxious, especially when your foot's not in it. Sounds awesome with catted h-pipe (went with JBA's myself).
you don't need a full tune- If you have a local shop that works on ls1's they most likely keept a tune for headers that they can work off of for your car. Most shops charge about 150-200 for a basic tune and up to 400-500 for a full tune. I would reccomend a tune a tune either way- it will only help you.
There's nothing wrong with running open headers. Lack of backpressure may hurt low end torque a little, but it won't wreck anything or cause the engine to run poorly.
