Open filter, 10000th

Hi to everyone! I bought a TT-R (as you can see below) not too long ago and I already bought a few things for it (audi dealer meant SAMCO, POP-OFF and Eisenmann are mandatory, otherwise it’s not fun) Now I have a hundred thousand questions for you: 1.) I have Eisenmann ESD+VSD with TÜV, about 200km on it, but almost no difference to the original system… will that still be? 2.) Which POP-Off? 3.) Which CHIP-Tuning? Have you heard from UPSOLUTE? www.upsolute.at …….Chip for 399 Teuros?? 4.) I thought, hasut times coal out……… bought me a horny open air filter (believe newspeed or so!) pics there afterwards! 5.) What would you recommend me to do? Optically it fits so far, just wants to draw the BMW “Hey crass-man types” with style one over your carpet-reels! dear greetings, C.
