GPHeaders’ 426 Hemi Header Mockup Kit allows you to design a set of truly custom headers without the vehicle ever leaving your location. We supply our customers with mockup header flanges and collectors along with our adjustable aluminum mockup elbows allowing you to design any header imaginable. These mockup header components are sized for PVC tubing which are used to easily and quickly connect the “bends” of the header.
When the mockup is complete, you ship the header back to GPHeaders for it to be replicated from either Mild or Stainless steel. The purchase of this kit will serve as a credit to the final price of custom headers. Below is a guide to what your headers will cost.
4 Cylinder 6 Cylinder 8 Cylinder
Mild Steel $900 $1350 $1800
Stainless Steel $1100 $1650 $2200
Prices above are for guide only. Prices may increase or decrease depending on material, tube size, collector style, header finish, etc. Since every application is unique Contact Us for a quote on your next set of Custom Headers.
