    Keep this post for HELPING people.

    HPT is sold internationally. How many people posted here can speak two languages well? This is a forum for enthusiasts to help each other, not immature individuals to mock others.

    Now to the original post, as others have commented DTCs need to be properly set for ("off road use") the new exhaust. Open the DTC section in the scanner and disable those codes and tests. This is very common after doing exhaust.

    With all those codes it looks as if the rear O2's are unplugged. He never said what exhaust mods. Headers or just cat-back. But it looks like the rear O2's are gone.

    Hi mate,

    First up, it would help if you put in your signiture in your forum profile where you are located so people know where you are from.

    To delete the rear o2 sensors in your tune -

    1. Open the tune in the editor and click the engine diag tab. you will see under the general tab the catalyst test and post o2 test boxes, set both to disable.

    2. In the engine diag tab click on the sub tab DTC's, using the list you posted earler go through one by one and set each code to you are seeing to "3 - No error reported" on the right hand side, also untick the "ses enable" box for each code if it is ticked.

    3. Refash the modifyed tune, drive and comfirm that the scanner is not reporting any more codes.

    It certianly seems from the codes that the rear o2 sensors are not even connected, if your new exhaust has no cats or bungs after the cats for the rear o2's then so be it, however if you can have them connected than i would hook then back up, it will minimise the amount of codes you have to turn off.

    Please also note that what i have described here is for "off road use only", ie, you will likley fail an emmisions test by doing what i have described here

    If you have any dramas then post your tune so we can see it.

    Merry Christmas
    Steve
