What is the possibility that i'm gonna get a SES light when i install LT's and 2highflow cats?

 

you'll be fine if you leave/put in proper o2 sensors like stock has.

 

The Magnaflow cats have bosses for mounting both sets of O-2 sensors. The ECU monitors cat performance by measuring what is going to the cats and how clean it is coming out. Many custom tunes will allow the rear set of sensors to be truned off, so it does not matter how well the cats work. I installed a set of the Magnaflows with a stock, unmodified ECU and had no problem, but the cats were fresh and clean. I did not run them long enough to see any long term effects.

 

have not been able to reach my tuner to figure out a chip option if the light comes on.. I do have a pair of MIL eliminators..will those work the same?

I installed Dynatechs and high flow cats...never had a light come on...
