I wonder if they have taken into account a replacement exhaust system. I'm in the process of replacing the whole system with the exception of the cats (yet) from down pipes to mufflers with a complete flow through racing system (hamann) Since the cats arent being replaced but the rest of the system will be less restrictive i wonder if there will be an issue with the software since this and most other updates are with completely stock power.

I have emailed HARTGE with all the new component details and they just got back to me telling me that they are investigating weather or not it will make a difference.

Im thinking if you are just replacing the muffler at the rear this won't really matter...but replacing the down pipes and x pipes with larger diameter ones and eliminating the middle resonator and mini muffler, it might??

Just some info i figured I would share since it might make a difference.
