I want to set my stock manifolds with true duals. Will I need to add o2 sensors or can I keep the stock two? I’m thinking I can keep bank 1 o2 as is and just space bank 2 o2 out to trick it so I don’t get a check engine light nor any performance issues? Any thoughts and or tips?
not going to run any cats.

 

How many O2 sensors do you have?

 

Only 2. Might just plug bank one in at one pipe and space out bank 2 to trick it.

 

Then you just need one near the manifold, and one after the cat. If you don't have a cat, the non-fouler trick will probably fool the PCM into not setting codes for the missing cat.
