Track day & Noise level test
Hi
Has anyone had a noise level test on their 2013/14 F10 M5 as required on many trackdays? I am running the Akrapovic exhausts as well, so anyone with some Db data would be useful in deciding whether I need to visit a track and getting it done in advance of a booking I appreciate that every car will be different, but some indication that I may be well within or over the limits would be appreciated. Benchmarks are 105 Db for static test and 92 Db for drive past. Thanks |

Now I know why no one has a comment - you can't get the car to meet the test standard
Just been to Brands Hatch for a free noise level check. I then realised that the car is limited to rev to only a max of 4000rpm and you need to hit 3/4 of the red line range (5500rpm) for the static test! At 4000rpm it read 89dB. Has anyone done a track day (with the CP or Akrapovic exhaust) and if so, we're you taken off for making to much noise? |
Appreciate
