The RCM 3″ stainless steel open neck de-cat downpipe is designed to fit Impreza’s from1992 onwards. (Not suitable for twin scroll turbo). This exhaust has been designed to cope with the increase in air volume from engines producing an excess of 350Bhp. The fantastic, open neck design offers minimal exhaust back pressure on the turbo and offers excellent turbo spool characteristics. Hand crafted using high quality stainless steel pipe work and flanges, it removes any kind of gas flow restrictions, resulting in excellent increase in response and release of power from your Impreza engine. Incorporated into the assembly is an extra lambda threaded boss for performance mapping. Please note that fitting RCM328 will alter the engine’s emissions.
