Sharing from @lmfscrew: Long Tube Header Complete Install

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.

Fast shipping and great quality!!

Very fast shipping arrived sooner than expected. The quality of the headers looked great and everything went on with great fitment and no issues like some people were stating . I used Gm multi steel gaskets and Dorman exhaust header bolts instead of supplied gaskets and bolts.

Thank you for your comment! Looking forward to receiving pictures of your feedback!

Satisfied Purchase

Great fitment, minor adjustments needed. Only has 2 O2 sensor ports so I have to drill and weld 2 more into Y pipe. Fits surprisingly well for 4x4 applications too.

Hi, thanks for your comment! We look forward to receiving your feedback pictures!
