C5RS6KID

Hello I recently turned 16 and my dad upgraded to an c6 s6 wagon and I got/bought his 2002 a6 wagon 3.0 v6 s-line of of him and it's not fast enough I wanted the 2.7t bought there nearly impossible to find in the wagon form. Is there any mods I can do to it. I did a muffler delete and she sounds nice now. My brother (17) bought a 2000 s6 wagon and I want to whip his ***. In mine. My mom is getting fed up with our bs cause there's 3 white wagons in our drive way and she has just bought a 2014 veloster turbo. Thank you!
