Here we have a good used pair of fully functioning left and right side exhaust catalytic convertor downpipes removed from a 2013 Audi S7 with 4.0t engine, This should fit many 12-18 Audi S7, S7 and RS7 as well as others. We are also parting out the rest of the car so If there's anything else in particular you need otherwise please send an email so I can list it on ebay for you.
