I did a car track day at CC on Friday. Mine was one of 6 cars that failed the noise test (which is the same 105 dBa @ .5m 45deg). Noise is a funny thing as my car didn't sound any louder than others that passed. But I do know that my car is quieter than any of my bikes... If you're doing a trackday before the DD round then have a backup plan to quieten it down some how. |
