But how close do you need to be. My road cerb is about 121db so id assume that would be way to high??

[Graham]

sorry i meant


very as in they are very strict.... over 105 and you'll be very lucky to get out... 106 maybe if their in a good mood but you need to get it under 105 to be sure you dont have a problem...


the ajp tuscans manage it so its easily possible in a cerb,

Bear in mind that each 3dB is *twice* as loud, so your 121dB is 16dB over, which is as near as makes no difference 40 times the limit. IME they might let you off with 1 or 2 dB, if you're lucky, depending on venue, but 16dB? Never in a million years.

On my Cerb, de-cat with a standard box is 103 to 105 depending on where? With ACT additional cans 98. You obviously have a decat with the two independant sports exhausts.
No difference in power.

My road one is just a straight through system. Just not sure what to put on the racer yet. The standard back box seems a bit heavy.
