Some time back there was a very short article by Andy Hollis about repacking a sealed muffler. Anyone else here repacked a muffler that is not intended to be repacked?
I have a Spit bodied GT6 (with a Mazda diff like the Ro-Spit, thanks GRM - I have not sheared (Triumph) diff teeth now in the better part of a decade). I have a turbo tube muffler below the driveshaft and a pair of (Dynomax?) mini turbo mufflers at the end. While I like the sound / tone of the exhaust, I want to make it more subdued.
Based on an internet search, it appears that stainless steel wool lasts much longer than fiberglass. I found a source local to me and ordered a small roll of course stainless wool and a sheet of stainless wool with a stainless screen mesh. Based on my muffler configuration how should I place the material?
My tail end of my GT6 exhaust: http://i290.photobucket.com/albums/ll272/aribert/Triumph/Sight_2016_06_20_194054_1001_zpsd45irfg4.jpg I cut open one of the cans (I made a jetting change last fall that reduced the fuel mileage by 4 mpg - it shows in how the holes in the tubes are almost completely plugged: http://i290.photobucket.com/albums/ll272/aribert/Triumph/Sight_2016_06_20_194054_1001_zpsd45irfg4.jpg In hindsight I think I should have just cut out the center between the two baffles. I could stuff the roll material thru the existing holes in the baffles. I also did not realize that there were two layers of metal - On the 2nd unit I intend to stagger my cuts so that there is overlap between the layers, easier when its time to weld things back up. This is what the two materials look like http://i290.photobucket.com/albums/ll272/aribert/Triumph/Sight_2016_06_20_194308_3681_zps2l1reqvk.jpg
I bought the stainless material before cutting open the muffler can. And foolish me, I cut the 8.5 x 20 sheet in half before opening up the muffler. The idea is to wrap/weave the sheet between the two tubes and use the roll material in the ends.
Your thoughts/suggestions?
