I am struggling to get much below 105db's!
Although it says that 93db's is the limit I wonder if that is at idle?

IVA is now the UK test for compliance with the EC construction and use regulations.
It requires 99dbA at 3/4 of 'max power' revs.

So where does a figure of 93dbA come from?

Dont think this aplies here..... most of the Born again bikers on the HOG's in my Hamlet would have trouble passing 110db on tickover !!!!

Oh yes and Cat's are kind of optional aswell, and was so looking froward to fitting them to my LS7.... NOT
