In that case, my SL Carbon cans are louder than I think they are.

(Mind you, setting off some car alarms in an undercover car park should have been a big clue, eh?? :smt017 )

Oh and 98dB is the limit for things like Donnington or Brands 'Quiet' days. It is lower on the road.. unless you ride a really old bike..

Knew it related to something quiet.


I've never managed under 100 yet when Ive been tested with race cans, but if the cans been repacked most twins seem to register about the 100 - 102 mark.

One word of warning though - my bike registers higher on track days than on race days - the track day testing doesn't tend to strictly follow the ACU proceedure about revs and distance (they dont have to - it doesnt apply - and its their track so they can do what they want) and tend to register higher.

My straight through wolf cans came in at about 97db @ 5000rpm at Cadwell earlier this year, well under their 105db limit and I always thought they were very loud. Full throttle would have been a lot louder obviously, but they were only testing the big twins at 5k.
