I bought a pair of OEM cats from a 2013 s4 to replace the ones in my 2011. The bungs for the O2 sensors are in a different place! Will they still fit?

Are they different part numbers? Seems like this sort of research would have been important before purchasing.

You're right, but I had no clue, as all the aftermarket cats fit on both vehicles, the only thing different is location of the bungs.
