Professional fabrication tools designed to help enthusiasts build high-quality manifolds.

Building your first exhaust manifold can be challenging.

Most of the time is spent cutting, adjusting, and trying to make the pipes line up correctly.

Small geometry mistakes early in the build often lead to:

• pipes not fitting well in the engine bay
• having to cut parts apart and redo them
• wasted tubing and hours of work

The GFAB hobby header block kit simplifies this process.

It helps you position and hold the runners in place while you mock up the manifold, so you can focus on building instead of constantly fixing alignment problems.

The result:

• easier runner positioning
• cleaner geometry
• less wasted material
• a smoother first manifold build
