I did a GSR swap into the hatch, and it came without an o2 sensor...For me to have the sensor since its supposed to be located in the rear of the motor, do I need a new cat for it to plug into? how do people go about this since civic o2's are up front on the header? did the swap myself, and this is the last question to finish it all up. Thanks! Also, if anyone knows where to get one for a descent price let me know...I don't need a wideband, just the gisser one, let me know where to snag one...thanks!
