Japspeed's Decat Downpipe compatible with the Subaru Impreza New Age replaces the standard restrictive downpipe and catalytic converters with a stainless steel, one-piece item. Increasing the bore of the downpipe and replacing the restrictive catalytic converters allows the exhaust gasses to flow much more freely, increasing the power output of the engine.
