This video features an amazing black Audi RS3 Sportback 8V in action during the SCC500 Rolling50 1000 supercar event in Germany. It's equipped with a very loud decatted Bull-X exhaust system, it got a stage 2 ECU software by THT Performance. Engine output is 492HP. The backfire exhaust sounds are just phenomenal!
