I'm currently running the Cobb Accesport stg2 map and I'm going back to the stock catback. I have a few questions before I make the move.

Will the stock catback still be safe to drive with the stg2 mapping? Or will I have to go back to the stock mapping? I also have a dp and hfc cat.

 

Can somebody help me?

 

Noone? :]

 

Yes, it will be fine to drive for a short term period. However, the stage 2 map requires a DP and TP/HFC in order to emit exhaust gases and keep lower EGTs so I would just flash it back to the stage 1 map until you put back on the DP and TP/HFC (flashing only takes 1 minute lol).
