it's pretty weird inside the kerker, it might be missing something, i always forget to get some images. i use the insulation off the garage door, and always have, but the kits all have a specific size length of wrap, that i see, and it looks kind of like not enough or it'll blow out fairly soon. and it's not the cost, it's that the sound and power takes a dump. i didn't get to check the messages so i just stuffed it full of glass. the whole thing packed, it's got some weight to it. inside of that tube is another short section of smaller solid hollow tube.
i probably did it wrong, but i take the cone off, pull the stuff out, and i pull the tube out and get a couple of wraps that fits close to tight and i wire it until i'm past the bend, so i'll put tube in, and from the solid piece to the cone is a long length of perforated pipe with nothing to back up the insulation to, so i just pack it, the glass in pretty tight, even the cone, so the whole thing works like the wire i guess. the glass is cheap enough, trash find, but is that too much? it runs like the stock muffler being that quiet, and only for the first 5 minutes did it seem to be too much, after that it runs as good as ever, high on the r's easy and pulls good.
