Do headers improve performance?
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. During the exhaust stroke, a good way for an engine to lose power is through back pressure.
What headers add the most horsepower?
Medium and long-tube headers allow an engine to make more horsepower at high rpm.
How much HP does headers and a tune add?
You can get significantly more horsepower and a more aggressive car if you install headers with a tune.

After installing headers and tuning, you can get up to 50 additional horsepower on your car.

After-market exhaust systems are almost always less restrictive than factory exhaust systems. However, that doesn’t mean that adding an after-market exhaust will always result in more power. Depending upon your vehicle and the system you choose, an after-market exhaust can add as much as 50 horsepower or as little as 2 or 3 horsepower.
How do exhaust headers work to improve engine performance?
An exhaust header is a bolt-on accessory that makes it easier to push exhaust gases out of the cylinders, improving the engine’s performance. The power stroke is the only stroke that generates power (the other strokes drain energy), so an improvement in their performance can make the engine more efficient.
