One side Catalytic converters is missed

[haydar alameen]

Hello every body , I noticed the bank 2 cat converter was taken off by the previous owner , the bank 1 is present
I want to ask if there is effect on fuel eco ? As my car very thirsty, I do every thing for that but the problem the same

Yes, one bank will have higher back-pressure and that will skew the air/fuel mixture. Adaptations might be able to compensate but it is unlikely....

It’s worth to buy one ? ( regard the economy )

Only if the adaptations are vastly different one bank to the next:

What is the limits of these values ?
And it’s the same of short term and long term fuel rail ?
