R RODSCALIP5 : 10 MS3 Jan 18, 2007 #1 I am looking at getting the HKS cat-back. From what I have read it deletes the 2nd cat. Does the 2nd cat have an 02 sensor or not?

T tru-boost Member : 2007 sunlight silver speed3 Jan 19, 2007 #3 i believe there is an o2 sensor before the first cat, that is used to read a/f. and one after the first cat, that is for obdII emmissions readings. deleting the second cat should do nothing but add power !!
