Welcome to the forum mate... and congrats on the car.
Maybe i am spoit with ecurie's stable, but there does not seem to be any aural drama to the car, i know i am running it in, so i am not using the engines full rev range, but i dont get any engine / exhaust excitment. The Cooper S Works has an awesome supercharger / spluttery exhaust combo which i loved. The turbo whistle is pretty cool though
Nah its not just you... I had exactly the same feeling about my Edition 30 when it was new as it sounded lifeless and really smooth - I did have a Golf R32 before however and they sound awesome. However, after almost 5000 miles it has opened up a little and you can hear the engine a lot more - not as good as the R32 of course - and there is a clearly audible turbo whistle reminiscent of the Mk4 GTI Turbo and a lot louder compared to the standard Mk5 GTI.
