Got the bassani x pipe. Getting a code and wont pass emissions. If i tune it back to stock will that work? Also, will tuning it back to stock mess the car up, since i have a bunch of mods on the car? I know it wont run right, but running it wont destroy anything will it?

i have the tune from brenspeed turning off the 02s, but it wont pass emissions unless the 02's are on. when i tuned it back with the 02's on, i still get a code popping up. Apparently, from what i read on here, i cant pass the emissions with that code popping up, so going back to stock could work? or putting back on my original h pipe (which is way to much work)

i failed as well because brenspeed turned off the rear o2s. call them up and tellthem to send you an emissions friendly tune so you dont have to return to stock .

Tell them you need the rear O2 sensors on in a tune, along with your other mods (CMDP and JLT CAI).
