I am about ot buy an off road mid pip to replace my stock pipe. I know that I am going to need to get some MIL's so I dont trip my O2 sensors.

How many MIL's will I need to get. I know that the stock mid pipe has 4 cats....so will I need 4 MIL's

If I just answered my own question I just want to make sure I dont waste any time or money.

thanks in advance.

you need 2 mils. one for each rear o2 sensor, and i'm pretty sure they are usually sold in sets

Only 2, theres only 2 o2 slots on an o/r midpipe

correct, only the back (downstream) o2's will throw a code
