RX1/Apex Header Mockup Kit


GPHeaders Yamaha 1000cc RX1/Apex header mockup kit is the perfect solution for your next custom Yamaha powered build. With this kit, you can design your own set of truly custom headers that fit your application perfectly instead of hacking apart a set of the factory headers or building your own which requires many hours, special tools, and in the end will cost about the same. Our Rx1/Apex header build kit is becoming very popular for a variety of custom builds such as dune buggies, RZR side by sides with Yamaha engines, airboats, and experimental aircraft to name a few.

We supply our customers with mockup header flanges and collectors along with our adjustable 3D printed 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. These headers are available in either a 4into1 collector or a tri-y design.

The purchase of this mockup kit will serve as a deposit towards the price of the finished header. A typical price for a 304 stainless header built with true merge collectors is $1300. 321 stainless is also available but will need to be quoted once the mockup is complete.

If you are looking for a manufacture to produce headers for your next project we would love to chat with you about our private labeling.
