cartridge

Gents, need some advice and views. Has anyone replaced the front Sachs guts of the v4 Tuono's with the pressurized cartridge set from Bitubo? Is this a mod worth doing? Appreciate insights and best practices!

I bought an Aprilia titanium exhaust to replace the standard dustbin exhaust. I wanted lighter (tick in the box) and I wanted louder but I understand from the seller that it is very loud, measured at 105dbA on a track day! That sounds too much & likely to attract unwanted attention from the law...
