Japspeed's Downpipe & Elbow compatible with the Nissan Skyline R32 & R33 replaces the standard restrictive downpipe with a stainless steel, 3″ one-piece item that bolts directly to the turbo. Increasing the bore of the downpipe and replacing the restrictive cast turbo elbow allows the exhaust gasses to flow much more freely, increasing the power output of the engine.
