Made of finest SUS304 high-grade steel downpipe from SRS

Our exclusive SRS with 200 Cell Fast Flow Sports Cat, fits all models of  Subaru Impreza Turbo WRX/STI from 2001-2007. Direct replacement for orginal downpipe, allowing turbo to spool up much sooner and improves power. Flow rate is only very slightly lower than that of a de-cat downpipe, due to the high flow design of the sports cat. 

Manufactured in 304 stainless steel with open neck (Bellmouth) design, ø pipe 3.0" (76mm) and 2.5" (60,5mm) connection at centre section flange. Maximum power from your Subaru Impreza AND pass all emissions emission rules !
