This RCM exhaust centre front section is designed to fit UK/Euro specification Impreza WRX and WRX/STi from 2001 to 2005.
This simple yet effective modification is designed to allow a freer flow of gases by removal of any restriction caused by the secondary catalytic converter releasing extra power with a slight increase in noise.
It is made from the finest quality 2.5" stainless steel pipe work, flanges and has been hand crafted for your Impreza. It also incorporates a threaded boss for the secondary lambda sensor.
It fits either the standard downpipe or RCM329 as well as RCM347 or the standard rear centre section.
