Exhaust Header VS Manifold: which is the better choice?

The primary structural differences between exhaust headers and manifolds lie in their material and design. Exhaust headers are crafted from lighter, thinner steel, whereas exhaust manifolds are typically made of thick iron. Headers are also longer in design, which plays a significant role in performance. While exhaust manifolds tend to create back pressure, which hinders engine performance, headers solve this issue by providing each cylinder with its own dedicated tube. This ensures that exhaust gases can exit freely, without the creation of back pressure, resulting in a boost to both horsepower and torque.

For custom builds like T-Buckets, Sprint Cars, Roadsters, and Hot Rods, upgrading or replacing your exhaust headers is crucial for maximizing engine performance and sound. Flashark headers offer the perfect solution, providing improved exhaust flow and a deeper, more aggressive exhaust note. Whether you’re cruising the streets or taking it to the track, Flashark’s direct bolt-on headers are designed for easy installation—no modifications required—making them a hassle-free, performance-boosting upgrade for your vehicle.
