Special GIANELLI racing wool, it is called in the jargon "silent hair" it is universal, very easy to apply and really special. It is the result of new competition techniques for ever less exhaust noise. The supplied bag allows you to easily fill 1 very large silencer or 2 medium-sized silencers.

It is also much less irritating than rock wool or even ceramic. When filling, remember not to compress the wool too much in the silencer, nor should it be able to move when the engine starts!
