I have true dials on my Silverado and about to change it up to true duals with a dual in dual out muffler to prevent popping. What I was wondering is do I need 2 wide band 02s for tuning in b1s2 and b2s2 Or can iI just run an x before the muffler and put the wb02 in the x? I will be gutting my cats so thats not a worry

 

Anyone?

 

Just run one and put it in the drivers side behind the headers/manifold.

 

I agree!
