Bought it from Gruppe-s never used it cause I had an o2 extension welded on my downpipe instead.

$10 picked up or shipped

How does this thing work. I need to install my DP soon and have no idea how the electical cel fixes work.

 

It's an electrical resistor with 2 wires coming off each end and you spice it into the wires leading to your rear o2 sensor. Pretty much you remove your rear o2, open up the white shielding on the wires, cut the blue & white wires and wire in the resistor between them. This prevents you from getting a P0420 cel by tricking the ecu into thinking the o2 sensor is operating at normal temp, when actually its much hotter because of no cats. I still have the instructions its really not hard. Just need soldering iron and electrical tape.
