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

Comfort Color is a trusted brand for comfort and durability. These are great!
Size: X-Large, Color: Blue Spruce, Number of Items: 2
Great price for two of these high quality Comfort Colors tees. I really love the color (a blue/green blend). So pretty. I find their sizing to be true to size and the quality to be great. Washes well. Dries well. Is comfortable and soft without being flimsy and thin. While these are called "heavyweight", it just means a nice, solid tee but isn't overly hot to wear. Very happy with them and I buy these for printing because they do well with decals and washing. These do not get wrinkly in the dryer either.

Love these shirts
Size: Small, Color: Watermelon, Number of Items: 1
Love the fabric. They feel so much better than some of the other shirts I have. They’re thicker and just feel nicer. Love this color too. Got a small and also have another color in medium. Both fit, just depends on how casual I want to look. I’ll be getting more!

Will buy again
Size: Large, Color: Washed Denim, Number of Items: 1
Great shirt! The material is very comfortable on my skin. It is a little tight in the neck but pulling on it ever so slightly fixed it for me, other than that it fits perfectly!

Great price; some fitting notes
Size: Medium, Color: Washed Denim, Number of Items: 2
The shirt looks good, good quality, and the price is pretty much unbeatable. Some notes of fit: compared to the Eddie Bauer men's medium legend wash (my standard), this one has a smaller neck opening and is a bit tighter around the chest. Also, the short sleeves are shorter than Bauer's. These aren't really criticisms, but they may work better or worse depending on the person wearing them.

Comfortable, Colorful, Soft, Affordable.
Size: Large, Color: Ice Blue, Number of Items: 1
These T Shirts are as good as it gets especially at the price point. All cotton, very soft, very colorful. Wash well. If you don’t want them to shrink, I suggest air drying them. I had an XL one for years and pretty much ignored it. Found it again and it’s amazing to wear to bed or around the house. At These prices if you need or want a T shirt, this is the one to get.
