I'm brand new so be gentle and I'm sure this topic has been beat to death but here goes. I installed a set of Texas Speed 1-7/8 long tubes on my '17 LT1 and now have issues with cat inefficiency codes (expected). What's the magic formula to make it go away. I know i could delete the DTC's and SES for the downstream o2 sensors but I'm pretty sure this will keep the monitors in not ready status. I do have to pass smog in 5 months so I would be a no go if that's the case. So what are my options in resolving this. Can't pulse timing be modified to allow for the sensor relocation? Thank you to anyone that can help!
