I have been looking around for a new back box. i mainly want one for the sound. i have heard about absorption boxes? would this be the best thing to buy or does anyone have any better ideas?
so you would only need 1 :grinning:
i,m just implying that absorpsion silencers are very efficient yet they dont slow the flow down like a muffler (as in the pic where the gasses have to exit the perforations of "in" pipe then enter the perforations of the "out" pipe
