I'm running catless mid pipes and I don't know what to do. I have 02 sims that I can use or I can alter my tune with my predator I think. What is the best way to go and why (help me understand what I will be doing)? Thanks.

 

As far as the best way to go, I couldn't tell ya. But I put the simulators on my truck when i cut my cats off and it was really simple and straight forward and have had no problems with them at all. They have been on for at least 6 months with 10,000+ miles.

 

i am pretty sure you can turn off the rear 02's with the predator.
