dB-killer for my Akra

I am looking for a dB-killer/eater for my Akrapovic full system, because I want to do some trackdays which have dB-limits and with this exhaust it is impossible to go there. A dB-killer will do the trick, but the problem is there doesn't exists no direct bolt-on because it's 'not for road use'...
I have seen on the site of Akrapovic that there is a street legal one for the pointy SV and I assume there is a killer monted on it. Will that one fit my exaust? The inner diameter of mine is 48mm and looks like this:




Or is there an other solution to lower my dB's?
Mounting my original exaust is no option, because then I need to remove the whole exaust-line and that takes too much time/work...

Cheers

you can get retro-fit db killers. Just search on ebay, theres a few on there normally.

Thanks for the advise, I will look for it.


Nobody with a pointy SV with Akra's over here?
