Header Modeling Systems

The Icengineworks Exhaust Header Modeling Systems allow you to simulate an exhaust runner using plastic blocks built to specific radii and OD. These blocks can be indexed and rotated to replicate cut and welded pre-bent tubes. Two kit sizes are available to cover 4 or 8 cylinder applications. See the Full Fabrication Systems for an all-in-one header building kit that includes cutting and clamping jigs.
