I recently purchased a 99 Interstate with 36,000 miles on it. The previous owner said he bought it with the piggies drilled out and he said it was to loud, so he bought another exhaust and put it on. On my way home, it sounded like it had an exhaust leak, so I decided to change it back to the exhaust with the piggies drilled out. When I took off the exhaust, I don't think there are any gaskets in there at all. Can't see to good anymore, but with glasses on and a flashlight, the exhaust port is flat with a copper colored "ring" that is flat with the exhaust port. I have new gaskets, and can't imagine the old gaskets being "crushed" in there that flat. I tried "picking" at the copper colored part with a small pick, but it ain't moving. So, when the exhaust comes off and the gaskets are out, is there a copper colored part flush up there in the exhaust port? I can't believe the exhaust gaskets could crush that evenly and that flat, but I ain't no mechanic and need advice. Thanks, Gary

Yup, that little copper washer looking thing is the factory gasket. Very thin, I suppose that's why they leak easily.

Happened to me!
I got MarkT's organ pipes installed this year at Mark's place. When we pulled off my old pipes they came out with two gaskets installed. I had replaced an old set earlier. So I had been running with two sets installed for years (at least since 2004, when I bought the bike).
I suspect you should not see cooper if they are removed. I can't imagine that integrating copper into the block would be practical. I'm pretty sure they are just in there real good.
Good luck,
GJS

If you see copper, it's those gaskets squashed flat. When you get them out they look like donut shaped wafers. As I recall, there is a small ramp shaped area that helps to get under them. Remember that the metal around them is aluminum, so be careful not to gouge it up.

Yes, take an ice pick or small screwdriver from the inside edge, they will come out. I usually put a little grease on the new ones to get them to stay in while you install the exhaust. Some have egg shaped the new gaskets a little to get them to stay in. If I tried that I would ruin at least half of them.  |

If they wont come out without a fight........I too ran two sets for a couple years. The first time I removed the pipes and looked I thought (like you ) that there was no gaskets......the second time I knew better and I removed two sets, but hey! running two sets didnt hurt anything so it you cant get them out (and you think its just one set), Id just slam the new ones in there and dont look back

Got this tip from MarkT when I couldn't get my gaskets out. Take a small screwdriver that you're no attached to and sharpen the edge sharp. Makes it much easier to get under the old gaskets.

+1 Ran that way from 2004 through 2012. Same story with me - my gaskets were smashed flat and I almost didn't recognize that they were there the first time I looked. These fiber gaskets are so thick I don't see how two or even three layers of the copper ones could hurt anything...  Unless... on one side you had a stack of copper gaskets on one header and only one copper gasket on the other headers on that side... might be hard to keep that from leaking... -Mike |

Well, I got the gaskets out. Then, since the bike is new to me and the exhaust was off, I thought I might as well change the rear tire (had several thousand to go) to a car tire and clean and grease the splines. Splines looked real good, cleaned it all out at the firehouse parts washer, new o-rings, grease, etc. Then, since the exhaust and saddlebags were off, why not try take the trunk off and try and make it a SuperValk. Got the trunk off, cut some slots in the mounting brackets, unplugged everything (thank goodness the plugs are different colors). Put the tire back on just now and it's getting dark, so thats it for today. A work in progress. Thanks for the help.

No tail light nor brake light when you lose the trunk.
You can get a used unit which are pretty good from Pinwall. Just be sure it is correct and complete with the wires and lens.
Some say a tail light from a shadow will work but I'm not sure it will. The lenses are interchangeable however.
