The CTS Turbo Cast Catted Downpipe set for 4.0T Audi C7 (S6/S7/RS7) is a bolt-on solution for increased performance. Their downpipe set eliminates the OEM cross over and includes the necessary harness extensions for the O2 sensors.
CAD engineered cast stainless steel collector provides unrestricted flow and 3″ piping runs all the way back to the exhaust connection.
NOTE:
We recommend purchasing new OEM gaskets for headache-free installation (part number 4G0253115D, 2 required)
