What are exhaust manifolds for?

Replacing your vehicle’s exhaust headers and system with high-performance components like the FLASHARK Exhaust Header can significantly improve horsepower and torque, while also enhancing the exhaust sound. This upgrade is an effective way to make your engine roar like an American muscle car, adding an impressive 8-20 horsepower to your vehicle.

Additionally, installing an exhaust system can improve your vehicle’s fuel efficiency, with up to a 0.5 mpg gain. Although this may seem modest, consider the long-term savings: If gas costs $3 per gallon and you drive 15,000 miles per year, you can save about $85 annually. Over the course of five years, you will have saved enough to nearly cover the cost of a complete cat-back exhaust system.

The FLASHARK Exhaust Header provides a direct, bolt-on fit for the specified models, ensuring hassle-free installation without any modifications, making it a cost-effective solution for both performance and efficiency.

Exhaust Header VS Manifold, which is the better choice??

The structural differences between exhaust headers and manifolds are crucial for vehicle performance. While exhaust manifolds are made from thick iron, exhaust headers are constructed from lighter, thinner stainless steel, which helps reduce weight and improve overall engine efficiency. Additionally, exhaust headers are longer than manifolds, and each cylinder of the engine is given its own tube. This design eliminates the back pressure commonly caused by manifolds, which can reduce engine performance.

Unlike exhaust manifolds, which create unwanted back pressure that hampers your engine’s power, FLASHARK Exhaust Headers allow exhaust gases to exit smoothly and efficiently, significantly improving engine performance. This leads to increased horsepower, torque, and a more aggressive exhaust sound that enhances your driving experience.

Whether you’re upgrading for street performance or track days, FLASHARK Exhaust Headers deliver the performance gains you’re looking for with easy, direct bolt-on installation—no modifications needed. With superior construction and a focus on engine optimization, FLASHARK headers are the better choice over traditional exhaust manifolds.
