Re: Full system noise levels
it is track specific and each track it is specific to the day. so for example, Brands Hatch in the UK is really restrictive and quite annoying with trackdays during the week is when the limit is at its highest and is usually capped to 110dB @ 50% revs. you can then look at the spec sheets for the systems you're looking at to see what they have them tested against.
Last time I went to Brands Hatch, I had a R1 '09 with a full akrasystem but put the db killers in and it passed at 96db @ 6k because that is where he told me to idle, which is stupid because it idls at 4k!
noise limits are annoying,but so are loud bikes
