Hi all, new to here, had a S4 before and sold it then had a Bentley Continential GT just got rid of it and bought a RS3 from main dealer Audi. To be fair to them they were very helpful and couldn’t do enough, driven the car out the showroom and all is well apart from on the motorway the exhaust noise is that loud couldn’t hear passenger next to me. Got home thought it may have been a problem with the exhaust flap as it made no different when in sports mode ect, we have a 3.2 mk2 TT and can hear the difference in the exhaust on there. I looked under the RS3 and it hasn’t got a standard exhaust fitted some one has fitted a loud aftermarket one by the looks of it there isn’t really a back box there? Audi should replace it with a OEM one for me shouldn’t they? I couldn’t drive the car long distance with the noise Would have thought Audi’s how ever many point check would have picked it up?
