hey guys how is everyone

ive been planing on makeing a home made silencer for my 77dt 175 for a wile now and had an idea after a mate told me how some one used one of these to silence his riffle maybe use a big oilfilter from a car and just knocking a hole in the top of it and whacking it on the end of the expanshion chamber just wondering if anyone has tried this or does anybody recon it will work or will the paper in it burn any idea's anyone? i can make a proper strait through one from chicken wire fiber glass and a tin cylinder but the oil filter would be quicker less time consumeing and instead of repacking just buy a new one there cheap as

hmm interesting idea personally i think the paper inside will burn after a while but modify the inside by using fibre glass like they do with exhausts
