Are all LS headers the same?

by Wilson Ellis | views: 271

“For the most part, all stock LS heads will use the same headers, but the LS7 heads and some of the aftermarket racing heads have a slightly larger port that is shaped differently and will require you to do your homework to make sure your headers will work.”

You might also wonder, will ls1 headers fit ls3?

LS1 headers fit an LS3 F-body.

With that in mind, will ls2 headers fit ls1? The header flange pattern will be the same, but if you are asking if the LS1 GTO headers are the same as the LS2 GTO headers, they are not.

Another question to consider, do different headers make a difference? The answer is yes, headers will boost performance – IF your vehicle is “prepared” for them.

Do headers add more 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.

Are all LS exhaust manifolds the same?

What headers make the most horsepower?

Medium and long-tube headers allow an engine to make more horsepower at high rpm.

What's better long or short headers?

How much hp do shorty headers add?

The headers will give you 8 to 15 additional HP gains, and come packaged with gaskets and the hardware needed for installation. Performance-tuned and engine-matched with performance gains at the lower to midrange RPM highway speeds.

How hard is it to install headers?

Tubes connected to each cylinder work together in a coordinated effort to ensure your engine reaches peak peformance. It is a labor-intensive job installing one of these to your own car, but installing a performance header is far from impossible. Some mechanical background will be helpful, as will a deep socket wrench.

How much hp do cold air intakes add?

Cold Air Intakes are said to improve your vehicle's performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn't enough power to put you back in your seat, it will give your car or truck a little pep in its step.

How much hp does a downpipe add?

It's generally accepted that installing a downpipe will add just 10 to 20 horsepower, but that gain is noticeable when the engine is revved up.

Are headers better than stock manifolds?

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.

Is a manifold the same as a header?

What's the difference between an exhaust manifold and a header? The structural differences between exhaust manifolds and headers are the material and size. Exhaust manifolds are made of thick iron, while headers are made of lighter, thinner steel. Headers are also longer than exhaust manifolds.

Where are Hedman headers made?

Hedman Hedders is the original, and still the premier manufacturer of performance exhaust headers in the world. Design and produced in their California manufacturing facility since 1954, no other header manufacturer offers as broad a selection of applications and design options in the industry.

Are shorty headers louder than long tube?

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 add 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.

What size headers should I get?

Horsepower OutputPrimary Diameter
200-325 hp.1 1/2 in.
275-425 hp.1 5/8 in.
400-500 hp.1 3/4 in. or 1 7/8 in.
500 hp. or more2 in. or larger

Do you need a tune for shorty headers?

Shorty headers are not enough of an aspiration change to require a tune, unless you are removing the catalytic converters at the same time.

Are long tube headers illegal?

16 Long Tube Headers

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.

Do you need a tune for long tube headers?

Long tube headers constitute as a major change for the exhaust aspiration of your vehicle's engine. To compensate for the added air flow, and the relocation of the oxygen sensors, a new or updated tune is required.
