hello people, wondered what ur suggestions are on making my new motor's exhaust quiter[its soooo loud]? dont really wont to change the back box as it was put on just before i brought it and i like the look and would like the sound of it, if it were quiter.[ it pops n splutters a treat] Do people think a different mid section or a silencer or maybe welding a coller in before and after the back box or somethin to reduce the flow abit [will this mess stuff up powerwise] would work?? any suggestions would be appreciated. cheers
