    You can get O2 sensor eliminators from a performance shop and you can then cut them out or hollow them without any codes being thrown. I imagine straight piping would be easier than hollowing, but that depends on how strict the laws are in your area. At least when hollowed, you still have a functioning appearance. I need to invest in some eliminators as well because with my exhaust, I have bypassed my existing cats, and I have to reset the codes every so often.
