RCM Open Neck Exhaust Downpipe 2.5″

The RCM stainless steel open neck, de-cat downpipe is designed to fit Impreza’s from 1992 onwards (not suitable for twin scroll turbo). This assembly consists of 3″ pipe work which reduces to 2.5″ where it meets the centre section. The fantastic, open neck design offers minimal exhaust back pressure on the turbo and offers excellent turbo spool characteristics. This is ideally suited to Impreza’s producing up to 350Bhp. Hand crafted using high quality stainless steel pipe work and flanges, installing this pipe removes the gas flow restriction caused by the main OEM catalytic converter resulting in a noticeable increase in both response and power from your cars engine. For Track Use Only. RCM612 exhaust fitting kit will be needed for this part.
