£48 delivered from Speedycom (no online payment, weird, though quick delivery), a sure-fired way of quietening down the Racefit, apparently. It has no wadding, so I presume it reduces the noise by cutting down the amount of internal metal meshing that is exposed to the atmosphere.
It’s made out of Titanium and weighs next to nothing. The welding is incredibly good. I have no idea if I’ll need to adjust my fueling map, but it’s no big deal to do with a Windows laptop and a usb cable.
I bought it as I’m only JUST under the noise limit of 105db for most trackdays and don’t want any hassle on the day of our next one at Brands Hatch on the 1st Oct.
