What Are Exhaust Headers For?
Boost Horsepower, Torque, and Fuel Efficiency with Corvette & Bel Air Headers
Upgrading your vehicle's exhaust headers is an effective way to increase horsepower and torque, giving your car the power it deserves. Whether you drive a Chevy Corvette or a 1957 Chevy Bel Air, installing high-performance headers can add up to 8-20 extra horsepower, while also improving exhaust flow and engine efficiency.
Not only do headers enhance performance, but they also provide a noticeable boost in sound, giving your car that signature American muscle car roar. Additionally, an upgraded exhaust system can improve fuel efficiency by about 0.5 mpg. Over time, this can result in savings of up to $85 annually on gas—enough to offset the cost of a new cat-back exhaust system in just a few years.
Sharing and affirmation from customers
Exhaust Header VS Manifold, which is the better choice?
The main structural differences between exhaust headers and traditional exhaust manifolds lie in material and size. Headers are made from lighter, thinner steel, while manifolds are constructed from thicker iron, making headers more efficient and durable. Additionally, headers are longer than manifolds, allowing for improved exhaust flow.
When in use, exhaust manifolds create back pressure, which reduces engine performance. However, with headers, each cylinder has its own dedicated tube, allowing exhaust gases to exit freely without creating back pressure. This design eliminates performance limitations, resulting in a significant boost in horsepower and torque. For anyone looking to enhance their vehicle, exhaust headers are clearly the better choice over manifolds, offering improved power, efficiency, and sound.
