if you want it quiet do what i done, maniflow larger centre silencer and 10" rear. its on a stage 2 lcb
Maniflow ( mild steel ) twin box aint that quite on mine but seems to have more basse 1275 with lcb, i think that the rc40 was about the quitest with a decent sound and ive have a lot of sytems to keep down the noise, loudest was playmini it made the 6x4 slabs vibrate around the back of the house
yea it will be going on a metro 1300 with a maniflow stage 2 hi-flow LCBi remember my twin box being pretty quite, is the rc40 quieter then? this vid is my old twin box maniflow tell me if the rc40 was quieter, well and tell me if your maniflow was like this as well just so im sure its quieter or louder
speak to maniflow, they fitted it for me
