I know every track setup is different, but I thought it would be interesting to hear what readings people have got from noise tests at the track. My silenced Orbisoud with it's sports cat was 92db @ Bedford with 4/4.5k revs I think.
Decibel readings
Ktec Ultra (Silenced) with standard cat = 91
BTB with standard cat = 93
Yozza with unsilenced de-cat = 99
All at 4.5k rpm. The chap with the Yozza was told off consistently at Bedford.

Yes I think it was quoted as 92.
The Yozza must be a nightmare most of the time! There's been plenty of occasions where I've been annoyed by mine on a long journey.

Scorpion 192 exhaust, standard cat, 88 at bedford.
Yozza is fine on long journeys if you keep the cat. Goes really quite at 70-85.

I think a decat makes quite a difference to the noise levels. I remember a guy at work had a standard exhaust with a decat and it sounded much more purposeful than mine at the time. Any ideas on levels for the prospeeds?
