Very different..... A4 2.8 & S4 are the same shape/ design, BUT
The A4 2.8 exhaust opening is 2.75" and the S4 is 3.25" to 3.50".... you'd need a custom fitment "sleeve" to make an S4 exhaust fit on an A4. I've personally tried to make an S4 aftermarket exhaust fit on my car, just doesn't work (insert much gnashing of the teeth here for the 2+ hours wasted on that little excursion) :-(. I was told that muffler shops could mock up something to make the fitment work, but I haven't tried that option yet....
The 1.8T exhaust is different from the other 2 in its design- the pipes don't lay out in the same pattern, so it's not interchangeable at all.
