1997 Mustang GT: Are there 1 or 2 sets of MIL eliminators on an offroad H-pipe?

rbailey1010 · 10-12-2007

I just installed a BBK O/R H pipe with MIL Eliminators installed on the back of the pipe (post cat location) and my check engine light came on after about 100 miles. Do I need 2 sets of MIL Eliminators (1 for the front of the pipe and another set for the rear)? Any feedback or opinions would help? I just installed a K&N FIPK today too so if this isnt the problem then I might have a vacuum leak or something related to the K&N......

You only need 1 set (for the rear o2's). I would make sure they are working properly.

disconnect the battery and reset everything then see what happens.
