i have an 06 vegas 8ball. it has the stock pipes and i bought it with 4 holes drilled inthe end of the mufflers. i do not know how far they go in or any details on what was done but it is still way to quite. i do not have to have anything crasy loud but need something more. i am on a budget and have been looking at the stage 1 kits with the mufflers k&n and remap. how much louder will these be? ive used the search button and can't find a whole lot checked youtube and the only thing i think i found was a short clip of a blue pin riding away. if anyone has any decent quality audio of these i would love to hear it. also my next option up in price would be the santa rosa clubs. any opinion on these. i would then have to invest even more into a pcIII or a lloyds unit. thanks in advance.
