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.

Great replacement parts!
Perfect fit for my 2003 Mercury Salt Water 150 2 stroke engine. Everything I needed was in the box.” “Good quality parts and saved me a lot compared to OEM.

What a lifesaver!
Model: 17749N, Model: 17749N
The usual box stores wanted around $150-$200 for a New and or Refurbished starter. The Ezexpreze 17749 was such a great deal and It bolted up nicely to my 1999 TJ with the 4.0 4x4! Its a great replacement, I've had it for about half a year but it starts with ease. I'll definitely get me another one as a backup at this price point!

I had a lot of noise upon startup and was concerned it was more serious than the starter. After purchasing this and installing. All is good and it really as some pro at start up now. Exact fit for 2013 JKU
