thought id try steel wool in my muffler repack for a change,ive used insulation glass wool thats very fine and i think it chokes too easy,it gets rowdy within six months,i figured the coarser steel wool wont block as quick?
wrapped it on with copper wire strand.

then topped it off with some glass wool and pulled down tight with copper wire.

still is a straight through design though.

because some peasants like open and loud exhausts here how it sounds without the tube,its shallow and thin sounding,then listen how much more tuned it sounds with the tube installed,free revving like this doesent reflect the true note of any system though,they need to be loaded.
open then repacked
