Noise Level 2.3 Duratec

[Keep it stiff]

I have booked a track day for May. I have just received the joining instructions and they say they are very strict on noise level.

Their limit is 100 db at 4,500 measured at 0.5 meters. Am I likely to have any problem with this?

I remember being tested with a rear engined car where it was easy to fool the tester as he could not see the tach from being crouched down at the rear, I can't see that trick working so easily!

Weather has somewhat restricted my Caterham running thus far, as a new car with less than 500 miles on the clock I have not been into this rev range as yet and even now my neighbours tell me it's not quiet!

100db is quite loud, but if you running the standard silencer I think you may struggle, on my Csr I replaced it with a 7" repackable can and that sorted out the noise.
