wide band afr

Hi All,

I have inline 6 cylinder engine with two exhaust pipes going back to end of the car before joing on the backbox right at the end. if you installing an AFR , would you either need 2 or join the pipes?

If you could place it after the exhaust merge so you can read all the cylinders that would be best.
