It can be done with intune but you would need a tuner with CMR software to do it for you. If you want to do it yourself you need HP tuners interface and software to disable the rear O2 sensors and DTCs. Even then you will not pass emissions as the O2 and cat monitors will not complete. Most states allow 1 incomplete monitor but not 2.But with the Itune, can I deleted the codes ?
Cat pipes cost like $550 each new while cat delete down pipes cost $300 to $400 for a pair. Having both gives one the option to install either when they want or need to. Not difficult to swap one for the other, a couple hours doing the swap on jack stands. I have swapped back and forth a couple of times this year.Why do you want to do this?
Cat-delete pipes are readily available.
