lexus is 300 awd 2018. i install invidia mid pipe and i have o2 code and i have no leaks. i tested the o2 with a computer and it's ok. I wrote to invidia he said try to put an extension o2 code eliminator that sells on ebay. I may try them the codes always come back.Do you have any solution? No one seems to have the same problem with occurs. what have you done.

For me I only had to go back at the dealership to get some stock exhaust gasket and then add them to the invidia kit ! Seems like they might not be providing the parts needed in the kit for the mid pipe.
since I added the stock gaskets the check engine light’s gone.


hope it helps
