So here is the current thought process for a few performance mods. Milltek or Borla cat back, CAI, and APR IC. I talked to the Audi Service department and should not have a warranty issue except on the listed parts. The questions are?

1. is this a good start?
2. Will any/all of these provide a real improvement over stock?

I have a lot of experience with American V8 cars. This is the first German car I have thought of modding.

Thanks for any input.
