I put LT headers and run them without cats, in just a few miles, SES light turn ON, i checked with and OBDII scanner and it shoots for the catalytic bank sensor. If i install SLP or Magnaflow catalytics, will this SES light turn OFF????

yeah it is because you don't have rear O2 sensors if you have no CATs, most people, like myself, get the code deleted by a tuner and only keep the fronts connected.

Dont buy that O2 simulators, i bought that ones and didnt work at all, the light came ON. I bought that ones because of the price, just a few bucks. In the dyno the guy told me that does ones didnt function. The ones that function usually cost aprox 100-200$.
But hte dyno guy told me that people are using some homemade invest to take the SES OFF and it has seen like it works fine.
But i want to go with cats, just to be safe.
