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.

 

sorry with the annoying question guys but any adise would be greatly appreciated.

thanks again

 

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

 

This should answer your question

You will need 2 mils, I got the steeda mils from americanmuscle.com

 

so I wont need any mil's for the fron o2 sensors??

 

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

 

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

 

thanks for all the replys....this site is great.

also I havent been on here for awhile and I just noticed the general discussion thread.

Sorry for posting this question on this thread.
