Starting with roughing out the nominal shape desired
A 3D scan of the stock manifold was imported for a design reference and to check clearance
Only portions of the manifold were printed to check fitment
3D prints of the manifold were used to check fitment and tune clearances
Functional prototype was then printed in Nylon with 20% carbon fiber content.
All the internals installed tight.
Charge pipe 3D printed and plastic welded together.
Ready to start testing!
