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.

  • Cast stainless steel collectors
  • Heat shielding to keep the temperatures down
  • 3″ Stainless pipes with sleeve clamps for easy install and maximum exhaust flow
  • Taper to OE fitment for direct fitment to factory or aftermarket catback systems
  • TIG welded
  • High Flow 200 cell metallic catalytic converters to reduce exhaust flow restriction
  • Includes O2 Sensor Harness extensions
  • Includes installation hardware (downpipe gaskets not included)

We recommend purchasing new OEM gaskets for headache-free installation (part number 4G0253115D, 2 required)

Stage 2 software tuning is required to remove the CEL, check with your software tuner.

Ok product for average shape
Size: Large, Color: White
ok for the price but didn't work out for us. I had one guy whose body is thick and one who is thin. Couldn't get the set to fit on top and bottom at the same time, pants were a lil see through, but still decent quality and price.

Wedding/Groomsmen: large Fit my husband perfect. The pants have a a spot with elastic so you can make them smaller if need be. Great color, lightweight and just as good of quality as Men's Wherehouse would rent.

Great value
Size: Medium, Color: Light Champagne
I bought this for my teenage son for homecoming, it really was a great value suit for the price. It even held up after a full night of dancing. He’s about 6 foot and 200 pounds So it’s very true to size
