Atlas Vortec 4200 T4 Exhaust Manifold

The Artec Performance General Motors Atlas Vortec 4200 T4 Exhaust Manifold represents a significant upgrade for the Atlas Vortec 4200 engine. Precision engineered and investment cast from SUS347 stainless steel, this manifold is designed to maximize flow and heat dispersion. Artec manifolds revolutionize the turbo manifold industry by utilizing an investment cast construction. This allows for smooth merging angles and the elimination of restrictions found in tight radius bends or runners. The result is a truly optimized manifold that offers consistent performance, resistance to heat pooling and cracking, and a refined exterior finish. This manifold is designed to accept larger frame turbos such as Garrett Motion G45s, Precision Turbo 75s and 85s, and BorgWarner S400s. It features a divided T4 flange and is machined to suit a Turbosmart 50mm wastegate, with the capability to run a 60mm wastegate if the flange is modified, as the runner is designed for its flow. The manifold has been tested on a number of chassis to allow for easy fitment in LHD builds. This product is designed and tested in Australia and comes with a lifetime warranty.
