I look at the ebay pictures of headers for the 02 accords and the hole for the o2 sensors seem to be on the back end where it connects to cat converter...so does that mean I need an 02 sensor extender or was that picture a sample pic? Anybody who has a header installed on their 6th gen accord or any accord plz reply! thx.

 

Just solder the four wires with the same size wires.

diy job if you know how to solder.
