What do Exhaust Headers do? 

Boost Horsepower, Torque, and Save on Gas with Headers and Exhaust System Modifications!"

Replacing a vehicle’s headers and exhaust is a way to add horsepower and torque, and it will also increase your vehicle’s volume. Want a car that sounds like an American muscle car should? This header will help your vehicle achieve that and it can add up to 10-15 horsepower.

Install an exhaust system means about a 0.5 mpg gas mileage improvement. While that might not sound like much, consider this: If gas costs $3 a gallon, and you drive this truck 15,000 miles a year, you’re saving yourself about $85 a year on gas. In five years, you’ll have saved nearly enough money to pay for a complete cat-back exhaust system

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.

Quality service

Enjoyed and admired the quality of the product. Had slight issues with the shipping but with one email stating that I haven't received my package. They was able to contact me via email and was able to send a replacement in a quick and fast shipping speed. So although there was complications, they have made the effort to compensate for the inconvenience so 5 stars overall.

Trey B.
Perfect fit, sounds good and looks great

Showed up a few days early I ordered both the headers and the catback the cat back unfortunately had a delay, so I refunded it but the headers sound good and give the car more power
