DESCRIPTION
This is an option for those with a LONG TUBE HEADER ONLY! Allows relocation of your FIRST factory O2 sensor far downstream to the collector with this 25" long plug and play extension. In addition to this extension for the first factory sensor, you will ALSO want our LONG extension for the secondary o2 (part 61-0098RD), so you can locate the second sensor downstream after the converter in the midpipe.
