Shown below is a custom merge collector and T3 turbo flange engineered by RK Designs for SM Works. The components were manufactured in stainless steel via metal additive manufacturing from our design files and subsequently used in the fabrication of a bespoke exhaust manifold for the Nissan SR20 engine.
