CTS TURBO AUDI C7/C7.5 S6/S7/RS7 4.0T CAST DOWNPIPE SET WITH HIGH FLOW CATS

CTS Turbo has done it once again, we made the perfect cast stainless steel downpipes with high-flow cats for the C7 4.0T platform.

The CTS Turbo Cast Catted downpipe set for 4.0T Audi C7 (S6/S7/RS7) is a bolt on solution for increased performance. Our 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.
