The RCM stainless steel open neck, de-cat downpipe is designed to fit JDM STi Impreza's 2003 to 2005 Blobeye models. (suitable for twin scroll turbo only).

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.
