How to repack exhaust

[Tong3]

I stole this from the VFRDISSCUSIONFORUM- thanks to HISPANICSLAMMER

Assuming you have taken off your exhaust.
take a drill and drill out the rivets- if your is riveted. Dont think you can repack exhaust can's that are welded...
"for a welded muffler, you can take it apart and repack it, but you have to be a very skilled welder (if you want it to look good), and you have to have a good cutting tool," Patrick.

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.

here is the fiberglass repack kit

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.

I plan to repack my Kirker can some time soon, and I came across this.
Hope this would help others, as it would me.

Nice write up -- even if it is stolen[8D] We'll have a DIY type mod forum soon and this'll be in it.

Man, that would be great. I cant wait to see what other members have to offer.

for a welded muffler, you can take it apart and repack it, but you have to be a very skilled welder (if you want it to look good), and you have to have a good cutting tool.
