How do they do the noise testing at Donny for the quiet days? Static test at the start of the day or noise meters at trackside - or both?

Tim,

From the ones i've done with various td co's, the circuit regulate the noise and usually the TD company checks exhuasts are standard BS marked or fitted with DB killers. There is a meter on the start/finish straight and you get pulled-in if too noisy. They are very strict and i suggest you check before going as on some days I've been many people have been pulled or not even got out. I have run the 900ss with the standard ali cans and the R1 with the standard exhaust with no problem, but some with DB killers do not get down to 98db.

I don't think Tim needs to do any trackdays, he's clearly too bloody fast as it is!!

Knowing my current luck with trackdays my pipe will be too loud with a dB killer in!

Might bring some baffle packing too lol

At Castle Combe with a db killer in mine was measured at 103.5db - but that was at 12k revs!!! - nobs
