It is typically a large-diameter metal pipe that is designed to handle high exhaust gas temperatures and pressures. The primary function of the downpipe is to channel exhaust gases away from the turbocharger and out of the engine's exhaust system. Downpipes are important because they can affect the performance of the turbocharger and engine. A performance-oriented downpipe may have a larger diameter, less restrictive design, and better materials to increase exhaust flow, reduce backpressure, and improve turbocharger response. Upgrading the downpipe can also increase the exhaust note and overall sound of the vehicle.
