Driver or passenger collector tube? I heard one tends to run a bit leaner than the other so I want to be in the lean tube.

why is one side leaner then other. Is it always driver or passger. Mines on the passage should i worry?

I put it in the driver side. That is where the tuner put his when he tuned the car so I should be good. Thanks for the replies.

If you have the stock exhuast then the cats are different from side to side. That has an effect. Plus, on any car I have ever seen the manifolds just aren't cast the same from side to side. I am sure the exhuast also contributes.

All you can do is tune for one side.
