Well it should bolt to the car, however you may need a reducer on the end of the S4 backbox as it might have a larger bore than the TDi.
You shure about it ? I think the rear box is about 3'' on the tdi after the cats...but i would double check that in the morninh though ! Thanks for the reply.

The vagcat diagram isnt very clear, but i think it suggests the S4 has a 65mm pipe, and the diesel has a 60mm pipe.
Not insurmountable though!
