I did a search and some reading about the woven gaskets used in our bikes.

There appear to be two of them for each pipe; one on top of the header and one where the muffler sits on the bracket.

Now, I have seen different names for the two, do these have different names? I have seen "interconnect" gasket and " crossover" gasket.

It helps with ordering the correct part.

I installed slip ons last night and used the old gaskets on the slip ons. Did not remove the pipes.

 

I found this post by Drewbone:


these gaskets are called "muffler interconnect gaskets."

For my 2009 Sportster Iron, they are HD part #65927-00, and they come two to a package.



Put them on/over the crossover pipe - NOT in the muffler, then slip your mufflers onto the engine pipe the proper amount, then rotate the muffler towards the gasket/crossover outlet [taking care not to screw up the gasket because they're fragile], align them, and press them down over the gasket/crossover outlet, slowly into position. They should slip over real easy. You have a small amount of play in the engine pipe to allow you some movement without screwing up the engine pipe gasket [you can loosen the engine pipes before hand if you want; just don't forget to retighten them after you're done with everything else]. Once they're in place and the mufflers are aligned with the crossover pipe bracket holes, hold the muffler in position and install the two lower mount bolts through the mufflers into the bracket and hand tighten them. Do the other muffler the same way, then add your center mounted pipe bracket, make sure everything's aligned, then tighten everything up. Slide your covers into position over the engine pipe[s] and tighten. Start 'er up and look and feel for leaks...

I guess this is the one below on the bracket

Great info, Oddjack. Thanks

 

I think what some people call "crossover" gaskets are the same thing as "interconnect" gaskets. The package on the ones I got says "interconnect", be sure to check them carefully when you get them, the first set I got at the dealership were damaged in the package, they are fairly fragile when not installed. I was able to re-use mine once, but the second time I changed exhausts, they looked pretty ragged.

 

edgeofinsanity,

Are you talking about the ones on top or the ones between the bracket and mufflers? Are they the same size and part number?
