MIL eliminators
 

is it necessary to have the MIL eliminators on the non-catted x-pipes??

unless your lucky and have one of the stangs that doesnt toss a code for not having then yes you would want them. they dot affect air fuel ratio so try it out if it tosses a light get them if it doesnt then you saved 50 bucks.

so how do i plug them into the pipe?? is it just a simple plug in or do i gotta drill the pipe and put them in?

they just plug in between the 02 sensors and the plug to the sensors

Yes, very easy install. I have the Steeda MIL's for sale if you'd be interested.

what u selling them for and where u located?

I installed gears and bought the Diablo sport to adjust the Speedo and turned off the rear O2 sensors so I don't need them anymore. I live in TX and will ship them to you for $45 total if interested. They have been on my car for about 2,000mi, not that it really matters.
