I have a sportex backbox on my 1.1 and have to admit the sound levels are stupidly high when picking up a little speed im now looking for a backbox that has good sound and not to loud or is there anyway of making the backbox i already have a little quieter maybe so it doesnt sound like a tank driving down the road lol
Time to change the Backbox

#2Ive just had one of these but was too loud for me lol. talked to one of my mates and he said that carnoiseur they are up lake industrial estate hav silencers you can slide in the exit of the backbox to silence them a lot. Where did you get the backbox from as ive just sold 1 of these on wightbay.
