Question: Do Long Tube Headers Require A Tune?

Is it bad to run headers without a tune?

just installing the headers voids the warranty and yes you do need to tune or you will be running too rich.

It will also never pass inspection if you have inspection were they hook up to the ecu.

you wont get much power without a tune..

Do long tube headers increase horsepower?

For long tube headers, the exhaust pipes are much longer and merge farther out. Because of this, each design impacts back pressure in the exhaust system in a different way. Longer port pipes result in lower exhaust back pressure. This means improved oxygen intake and a boost in horsepower.

Are open headers bad?

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.

Will open headers hurt my motor?

While running open headers may not hurt your engine, you could actually end up losing a little bit of torque and gaining horespower. Naturally aspirated engines require some exhaust back pressure to function properly.

Are headers louder than manifolds?

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).

How much horsepower do headers add to a 350?

The length of the primary tubing determines the effective rpm range, but headers can be worth 15-20 hp on the right application. Run on our restrictive two-barrel 350, the headers improved the power output to 248 hp and 365 lb-ft of torque, with consistent gains through the rev range.

How much horsepower does a cam add to a 350?

Replacing the 2G with a Q-Jet and intake alone can be worth 25-30 hp. Toss in a mild cam and cylinder head upgrade and the power gains really start to add up.

Do I need a tune if I get headers?

You dont need a tune after headers.

Will long tube headers make car louder?

Headers alone will not make it any louder. … Headers decrease restrictions, therefore increasing horsepower and sound. Many varieties are offered such as short tube, mid-tube or mid-length, and long tube headers.

Can headers damage engine?

Headers will not hurt your engine.

How much HP will 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.

How much horsepower do camshafts add?

Other cams can add as much as 50 HP or more, but the more power you get from a cam, the higher up the powerband the power usually starts. If you have a 224/224 cam (instead of my 205/212), you may have to wait until 2500 or 3000 RPM to get power, but it will be more.
