Add up to 8-20 horsepower, 0.5 mpg gas mileage improvement:

Enhance your vehicle's performance and fuel efficiency with FLASHARK exhaust headers and system modifications. By replacing your vehicle’s headers and exhaust, you can increase horsepower and torque, giving your truck the powerful sound and performance it deserves. Expect gains of up to 8-20 horsepower, making your engine roar like a true American muscle vehicle.

Additionally, installing this exhaust system can improve gas mileage by around 0.5 mpg. While it may seem small, over time, this adds up. For instance, if you drive 15,000 miles annually and gas costs $3 per gallon, you’ll save about $85 a year. In just five years, that’s enough savings to nearly cover the cost of a full cat-back exhaust system. The best part? It’s an easy, bolt-on installation with no modifications required—perfect for vehicles like the 2007-2014 Chevy Silverado, GMC Sierra, and more.

Exhaust Header VS Manifold, which is the better choice?

The structural differences between exhaust headers and manifolds are the material and size. From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.

Replacing or upgrading your exhaust header is necessary for both engine performance and sound. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound. FLASHARK offers many products to help you create your own custom engine headers. It's really easy and convenient to use: direct bolt-on, no modification needed.
