3D model description

This fabrication Kit Includes Everything you will need to fabricate a mock up tubular exhaust manifold for 2, 3, 4, 5, 6 and 8 cylinder exhaust manifolds in 1.50(38.1mm) Inch tubing with any wall thickness, and if there isn't a piece in there to your exact requirements drop me a message and I’ll add it as soon as I can.

This kit includes models with “start” and "end" at the end of the file name, these have an 8mm hole which can bolt to a manifold flange, or use the expander to connect to another tube, every bend has a start and end piece and currently a selection of straight pieces from 20-110mm. the bends come in a range of angles in 9 and 15-degree increments, with at least two different center line radius’, 1 Diameter and 1.5D, others can be added on request. Each is also marked in increments of 15 degrees so you can accurately note the angles at which two pipes sit when translating your design into metal.

The kit contains an expander that will fit into an existing pipe, a start or end piece then attaches to this to allow you to carry on from existing pipe work, or start a new downpipe from scratch. The expander works by using the bolt that the start piece attaches with to compress and expand inside the tube, it also pulls the start piece in to make sure that it doesn’t move while mocking up. Larger systems will need added s.
