I assume it is because of the hatchback nature, kinda how wagons are louder and drone more?
Somewhat irrelevant from outside the car.
You think so, why would the s5 be louder than a s4 or even rs4, I would assume more of the car is over the rear part of he exhaust and the hatch and trunk probably don’t help from a droning perspective? Just a guess. Trying to agree on your comment about being louder and the reasons why vs other 4.2 audis?
I have resonated. You told me to get resonated exhaust so I did lol. Maybe catless with resonator would be a sweet spot.
