Need a new back box! something not too loud

  1. #1
    Hello, i own a 1.4 saxo exclusive... I just had my tracking done yesterday and the people who did it noticed that i have a little hole in my back box, well it started to crack a little..So insteading of changing the standard one back on, i want something ,more sportier, but not too loud, are 3" very loud? i want something like 2" that is sounds tight and could increase few BHP. Thanks!
    Any recommended makes? eg sportex magnex.. etc.. Thanks!!
