This Audi S5 B9 exhaust sound is really amazing with IPE full exhaust system which includes a 200 cell racing catalyst converter. I also made a video on this car with IPE catback exhaust system only, you can definitely hear the differences. There will be more mods on my friend S5, please go follow him on his Instagram. Thank you for watching, please subscribe to my channel and follow me on Instagram as well.
