Exhaust Header VS Manifold, which is the better choice?

The key differences between Mustang headers and exhaust manifolds lie in material and design. Mustang headers are made from lighter, thinner steel, unlike the thicker iron used in manifolds. Headers are also longer, providing individual tubes for each cylinder, which reduces back pressure and increases performance. In contrast, exhaust manifolds create back pressure, which can limit engine efficiency.

Upgrading to Mustang headers like Flashark’s provides significant performance gains and a more aggressive exhaust sound. Offering a 10-15 horsepower increase, these headers ensure smoother exhaust flow and better engine output. Flashark Mustang headers are easy to install with a direct bolt-on design, requiring no modifications.
