Exhaust Header VS Manifold, which is the better choice?
Exhaust headers and manifolds differ primarily in material, design, and performance. Headers are made from lighter, thinner T-304 stainless steel, while manifolds are typically constructed from thick iron. Headers also feature a longer design with individual tubes for each cylinder, which significantly reduces back pressure—a common issue with manifolds that hinders engine performance.
By allowing exhaust gases to flow freely without resistance, headers boost engine output and improve exhaust sound. Unlike manifolds, which restrict flow and lower power, exhaust headers optimize efficiency and provide noticeable gains in horsepower and torque. Whether on the street or track, upgrading to headers is essential for anyone looking to maximize engine performance and achieve a more aggressive exhaust note.
FLASHARK's direct bolt-on headers make the upgrade process simple and convenient, requiring no modifications for installation. Experience the performance benefits with Flashark's expertly crafted headers, designed to enhance your vehicle’s overall driving experience.
SOME ITEMS YOU MAY ALSO LIKE
In addition to purchasing this product, Flashark highly recommends that you purchase Flashark and Spelab's new collaborative product, the silicone coolant hose kit; to replace the stock rubber coolant hose in your car's cooling system.
Are silicone coolant hoses better? Coolant hoses transport the coolant—a mixture of water and antifreeze—from the engine to the radiator and back. The coolant absorbs heat from the engine block and heads and then releases this heat through the radiator, where airflow dissipates it away from the vehicle. This continuous flow is crucial for preventing engine overheating, which can lead to severe damage or failure.
