the porsche 911 GT3 RSR's sounded nice as well although i could hear those cars for the next 2 weeks everywere i went even when i went to bed at night boy they sounded nice but a bit common lol.
i guess i did fail to mention the lamborghini murcielago RGT it sounds like no other lemans car ever seen or raced it does sound very very nice i wish i could see it racing especially the B racing lambo
and a special mention to the works zytek and jota zytek the backfiring from that car was something awesome it was like a helicopter gunship attack on a fireworks factory evrytime that car would brake and those flames at night the thing spat huge blue and white flames out like a machine gun at night
while the AER turbo cars flames looked like yellow candy floss all nice and fluffy somehow lol
