Additional Oxygen Sensor Bung for use with a Wideband Oxygen Sensor
NOTE: This item is NOT an OEM replacement pipe. It is meant to be used with the front section of the current version TurboXS Downpipe for the 2002-2007 Subaru WRX and STi. It is used to convert part number WS02-DPC to part number WS-DP by replacing the high flow catalytic converter pipe at the rear of WS02-DP. It does NOT work with previous versions of the TurboXS Downpipe.
