What does Exhaust Header do?

Boost Horsepower and torque, and Save on Gas with Headers and Exhaust System Modifications!"

Replacing a vehicle’s headers and exhaust is a way to add horsepower and torque, and it will also increase your vehicle’s volume. Want a car that sounds like an American muscle car should? This header will help your vehicle achieve that and it can add up to 8-20 horsepower.

Install an exhaust system means about a 0.5 mpg gas mileage improvement. While that might not sound like much, consider this: If gas costs $3 a gallon and drive this truck 15,000 miles a year, you’re saving yourself about $85 a year on gas. In five years, you’ll have saved nearly enough money to pay for a complete cat-back exhaust system.

Exhaust Header VS Manifold, which is the better choice?

The structural differences between and manifolds are the material and size. From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, 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. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.
