Exhaust Header VS Manifold, which is the better choice? 

The key structural differences between exhaust headers and manifolds lie in their materials and design. Headers, like FLASHARK’s B18 headers, are made from lightweight stainless steel and feature a longer, individual tube design for each cylinder. In contrast, traditional cast iron manifolds are heavier and create more back pressure, which reduces performance. With headers, exhaust gases exit more efficiently, eliminating back pressure and boosting horsepower and torque.

Upgrading to a performance B18 exhaust header is essential for enhancing engine output and sound. Whether for track or street use, FLASHARK’s Tri-Y design offers a direct bolt-on solution with no modifications required—delivering better airflow, increased power, and a deeper exhaust tone.
