@heyafb: The @valvetronic TRUE F1 Experience for the Audi R8 5.2L V10. This is JUST the cat-back configuration. No headers. This setup transforms the landscape for the Audi R8/Lamborghini Huracan, giving it sound characteristics similar to the 5.0 Gallardo, Lexus LFA, and Porsche Carrera GT. #valvetronic #r8 #v10 #f1
