Cast Downpipe Inlet and Outlet
The exhaust system features a strong, investment cast, T304L inlet and outlet designed to maximized flow and minimize turbulence. By casting the inlet, APR’s engineers were able to create a smooth and high-flow exhaust path that maximizes flow through swept blends and shapes that are otherwise not possible through conventional fabrication techniques. The inlet perfectly matches the factory turbocharger’s 77mm outlet and gradually necks down over a long distance to further enhance performance. The mounting flange and bracket are integrated into the casting, and TIG welding at the flex section ensures a clean inner surface eliminating turbulence, vortices and eddies to the highest degree.
