I just got a 05 S4 and am looking at performance mods. I am leaning towards APR for a tuning company but would like to hear a clip of their full exhaust installed. If anyone has this exhaust or knows where I can find a clip, please let me know. Also, any input on tuning companies would be appreciated. Thanks.

 

look online somewhere, i bet its out there. or cardomain.com. i heard theres a $19K supercharger.
