Treadstone takes advantage of the latest state-of-the-part technology when it comes to designing our high-performance products. Nearly all of our manifolds, turbochargers, and other components are fabricated from concept to reality using 3D computer-assisted design (CAD) programs such as SolidWorks, a CAD program specifically for designing mechanical products. This is Treadstone's new Trick Exhaust Manifold for the Chevy Tahoe, from computerized concept to working model. First, the wireframe of the manifold is drawn out in SolidWorks. We pay special attention to pipe design, diameter, and shape to maximize airflow and minimize turbulence. We also make sure that where the pipe connects to another pipe, such as the header primary to the collector, to ensure a smooth transition. All these efforts work to maximize volumetric efficiency, improving power, torque, and powerband. Faster exhaust velocities also help to improve turbo spool to help minimize turbo lag. The wireframe is rendered as a model to double-check for inner pipe smoothness, accuracy, and quality. A full-size model of the manifold is then created using a 3D-printing machine. Although it will not be used in application, the 3D-printed model allows us to double-check fitment as well as compare other specs in real life to ensure a top-performing product. If we find that we need to make a change to the model, we can do so at a lower cost than fabricating the entire model in CNC, then making a change. 3D printing allows us to have faster, better, and more accurate product development.
