SES light on with MIL eliminators?

[93Coupe]

this past weekend i installed my Bassani o/r X w/ MIL's and Mac 3" cat-back. first off i will say it sounds awesome and is a lot louder than i expected and as i was told in the other thread i did lose some low end power but top end it seems a lot stronger. anyways, i installed the MIL's and the SES light was off until i drove around for awhile and then came on. i dont understand why its on with the MIL's hooked up? any help would be appreciated

thanks

could be another code unless the code you pulled (if you did) was for rear 02s. It is also possible that one of the MILs could be bad or that the wire came into contact with the pipe and burned.

mils quit working at will and die,

could be your upstream o2's. my ses light came on after 500 miles due to these sensors. i replaced them w/ factory o2's and the light still came back on.

MILS do not last long. Just have the rear O2's turned off in a tune.

I have had this problem for so long! I assume my mils took a shit, but i have returned them once already. I like you dont want to change all of my O2s and have that not work either. I am so stumped on this subject.
