Sorry if this has been brought up before but I can't find the threads on it.



I picked up a couple of Harley mufflers this past weekend and want to install on a 80 CX500 Custom. Do I need to get new gaskets (after 30 years I'm assuming yes)? Where's the best place to get them (again I'm assuming I don't have to get them from a Honda dealership)? If I can remember someone mentioned they use Permatex instead of gaskets. If so, what type of Permatex and what's the benefits?



Thanks in advance for all the help. I find a ton of useful information on this site.

Being cheap and all that, I wrapped several thicknesses of heavy duty aluminum foil

around the pipes for a gasket. The foil is somewhat crushable and should be easily removed.

I had salvaged the gaskets but they fell to pieces when I tried to use them. Seems to be working.

The foil can be used to make the pipe larger is needed and also serve as the gasket.

Most honda dealers can still get the proper gasket material for the CX - they were used on a number of different models too. Failing that, I've see people use 'muffler tape' wrapped around until built up enough, and the 'permatex' solution as you indicated. I think Rob Davies pages had a description on how to make some out of Aluminium cans. Anybody remember or have a link to that part of the archives?

I haven't tried it myself, but I know a guy who used the sort of rope material that is used to seal around the doors of wood heaters or stoves. He reckons it works a treat, just wrap some around the pipe and then push it into the H box. It's available very cheap from most hardware stores.
