Exhaust Header VS Manifold, which is the better choice?

When it comes to improving engine performance, Sentra headers offer a clear advantage over traditional exhaust manifolds. The key differences lie in their design, material, and flow efficiency. Headers are made from lightweight stainless steel and feature individual tubes for each cylinder, helping to eliminate back pressure. In contrast, cast iron manifolds are heavier, shorter, and more restrictive — often reducing airflow and horsepower.

By allowing exhaust gases to exit more freely, headers unlock extra power and a more aggressive engine sound. This makes them a popular upgrade for drivers looking to boost performance both on the street and at the track.

FLASHARK’s direct-fit? are engineered for easy installation — no cutting or welding required. Whether you're upgrading for power, sound, or style, our headers are a bolt-on solution built for your build.
