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.

Good quality but missing parts

Only complaint oo have so far is that the kit was missing one of the 2-1/4” clamps . Luckily I had one laying around . And it really should have came with heat sheilds for how close it is to the fans

Hi, I apologize for the inconvenience. We don't have a clip with this product, we will collect your suggestion and feedback to our developers.

Manifold headers

Could definitely be better welds and include another flat clamp and studs. Look nice

Hello, thank you for your suggestion, we will collect your comments to continue to continuously improve our products!

Everything works very well so far, the car is not done at this time waiting on more new parts but it is running and your parts are good
