My mate, has bought a Rage backbox and had it fitted a little while ago, but now its annoying him, how can he quieten down its sound?
Cheers

take it off and go back to normal ...............lol
u can try and get a bigger silencer in the back box , fit another silencer but u may restrict power flow tbh it would b quieter but not as powerful or sumert like that .............changing it is ur best option .
