Car details: 2003 Audi A4, 1.8L Turbo (B6 Generation 2001 - 2005) (21 years of rust adds up)Hi everyone, I saw a good video on how to remove the front flex pipe, but you also need to remove the Catalytic converter to detach the front flex pipe.

Here is the link to that video that helped me get to this point: https://youtu.be/PXk5WWmdJNc?si=ib4PRWap7jbTvM8W (Thank you to that person!)

Another helpful video I watched for reference: https://www.youtube.com/watch?v=uV2Z6HOcDz8

Everything is going to be rusted, so it's going to take extra effort. Stay patient and dont break things..

You will need..
Size 17 wrench for the bolts
small, bendable ratchet wrench (5 inches or less, smallest head you can find)

I bought a new flex pipe on amazon that included a gasket from the front flex pipe to the CAT as well as a sleeve - Amazon UPC: 732829400661
