Has anyone down a cat delete/test pipe for their RS6?
I'm looking into it, making sure the software can be made to avoid a check engine light..
hoping for feedback :addict:

Call up Vast Performance. They do remove the pre-cats, put the O2 sensors further down the pipes, close out original O2 sensor holes, and re-coat the pipes.
These are known as the Piggie Pipes. Do a search for Vast Performance and call up and see if you can chat up with Mike.
