Im looking at putting a BBK X pipe with out cats on my 98 gt. As of now it has a home made H pipe w/o cats that the previous owner put on it. I have all the 02 censers hooked to it and I have no lights coming on , on the dash. But I noticed the BBK x pipe does not have the inlets for the 02 censers. So my question is were dose the MIL elimination connect? How many do you need? ( there’s like four 02 censers on my exhaust.) or should I get a tuner and eliminate it from there????

 

The x pipe should have all four bungs to hook up all four sensors. The MILs will go on the two rear sensors. If your x pipe doesn't have the bungs for the two rear sensors then just plug the MILs into the wiring harness to the car and leave the o2 sensors off but the front ones have to be on with no MILs on them.
