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

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

The CTS Turbo Cast Catted downpipe set for the 4.0T Audi C7 (S6/S7/RS7) is a bolt-on solution for increased performance. Our downpipe set eliminates the OEM crossover and includes the necessary harness extensions for the O2 sensors.

The CAD designed cast stainless steel manifold provides unrestricted flow and 3″ piping runs all the way back to the exhaust connection.
