Hey guy's I'm new on these forums. I have been doing so much research on this but I am starting to fail. I was wondering if anyone has removed their resonators and added a x pipe instead. I saw the thread about the s4's removing the center resonator and adding a straight pipe as well as adding a x pipe behind the down pipe resonators. Is this the same case as the 2010 A6 C6 3.0t? thank you guys
