I had a Brock's CT on my 14R and it always passed the scrutineering noise test at LSR meetings. I agree, it's a shame there's no H2 equivalent.
As far as I know the only system for the H2 so far which has an effective noise reduction baffle is the Vandemon. The owner of the company was asking about our permitted noise levels and claimed to have a solution.
Akrapovic also claim their full system is quiet but I've not seen any dB figures.
Comment on Remal's diagram above: You need to remember that a 10dB increase is perceived as twice as loud. Decibels are not linear. The Loudness scale is missing from that diagram for some reason but for example: the motorcycle is 98dB and you might think that one measuring only 108dB isn't too bad but it's heard as being twice as loud.
