i have a powerflow backbox but would like to try and make it abit louder. its letterbox style but the actual backbox only has a small hole to let everything out if you get me i.e. the hole doesnt take the shape of the letterbox.
what would happen if i made this hole slightly larger? or possibly drilled another one next to it?
.....not sure about this one, mite just get a new exhaust...i would still like to know though

i always believed that the smaller the backbox the louder it is!
no 100% sure but has proven true in the past with previous zhorsts
