Forum CEO HispanicSlammer Posted March 27, 2004 Forum CEO Share Posted March 27, 2004 Unbolting the hangers My D&D is sounding rather blown out these days, after about two years of general abuse I decided to finally repack the can. Start by removing the exhaust from the bike. Loosen all the straps Nasty! Road Grime Take off the lead pipe I used some OO steel wool and cleaned off the caked on road grime then some Mothers Polish to polish it back to shine. Take off the rest of the pipe You have to drill out the old rivets. Drilling off the rivet heads Punch out the rest of the rivet bodies Once the rivets are punched out you can take off the end caps. ?The D&D is one solid unit with both end caps welded on, some other units have sews and are easy to get apart. ?I had to use a rubber mallet and a soft piece of pine to push the end caps out of the tube. You can see the core is blown out I used a utility knife to cut into the old packing, you can see the blown out parts Use a wire brush to clean the core I wrapped the core with steel wool to prevent blowouts I read that wrapping steel wool around the core first prevents the new packing from getting blown out. You can get stainless steel wool here. If you use plain steel wool it will rust and desintigrate. http://www.steel-wool.com Fiberglass Pack kit ready! I was going to use wire to hold the packing in but the kit said to use masking tape - so I did. Compress the packing Pop Rivet the core back in I lined up the holes and tapped the core back into the tube, I used some high temp RTV on the end caps to seal them up, I had to pop rivet them on from below cause the pins would fall into the can if I did them from above. I hammered the rivet caps flat and then cleaned the pipe and polished the whole thing with mothers polish until it shined! ?I also removed the headers and cleaned it up with a wire cup on my electric polisher. ?Painted the headers with 1200 degree black ceramic paint. Sealed up the connectors and put in new gaskets. Quote Link to comment Share on other sites More sharing options...
Member Contributer mello dude Posted January 12, 2010 Member Contributer Share Posted January 12, 2010 (edited) So how much a difference did it make when you fired it up? - I got a carbon pipe I need to do this with.

Forum CEO HispanicSlammer Posted January 13, 2010 Author Forum CEO Share Posted January 13, 2010 So how much a difference did it make when you fired it up? - I got a carbon pipe I need to do this with. (Great photos and post.) MD I did not pack it as tightly as I should have, needed more glass packing. It sounded more throaty, still too loud - it was a D and D afterall. I ended up with a new Staintune the next season. I gave it to one of the wera guys on the forum for track use, it made good power. Quote Link to comment Share on other sites More sharing options...
AB-Oz Posted January 13, 2010 Share Posted January 13, 2010 I think I should probably re-pack my custom pipe, its now 7 years and about 90,000km old... Quote Link to comment Share on other sites More sharing options...

But the steel wool, while helping prevent premature blowout of the packing, may also be blocking the absorption of sound? E-Ticket Quote Link to comment Share on other sites More sharing options...

E-Ticket Staintunes are packed with nothing but stainless steel wool, they absorb sound, or actually the pockets of air do inside the wool. Stainless wool is just more resilent than fiberglass in terms of resistance to shock. Quote Link to comment Share on other sites More sharing options...

Guest Hammerspur Posted February 11, 2010 Share Posted February 11, 2010 Stainless Steel wool is what you need - regular steel wool will just rust away in a day or two. I've not tried this but heard it's very good in terms of sound mellowing and long term endurance: http://www.anvilfire.com/sales/k_index.htm Quote Link to comment Share on other sites More sharing options...

From what I read, you still need to do the stainless steel layer first. Just need to figure out how much of each I need. Quote Link to comment Share on other sites More sharing options...
