Harley Davidson mufflers for the CX500

30 Jun 2026 BigPeso33 Honda CX500 1978 A-spec 44

After a while of owning the CX500 I have decided it is time for the exhaust. It sounds good and clean but personally I like a more defined tone when riding. The CX forums provide a good information source on what mufflers to get and what fits.

It just so happens that some specific Harley Davidson mufflers do fit on the CX without major modifications! The pipes that I have they are from a Harley Davidson 1200 and they are known as: Screaming Eagle 2 pipes. When the chance popped up on Marktplaats I just knew that I had to grab it and make this the first CX on the internet with Scream Eagle pipes.

Nice pipes considering these are second hand and have been used for years on a HD 1200.

The pipes have a removable baffle that will be taken out, when the sound is too loud I will replace the baffles as I do not want the CX to be too too obnoxious. In the video below you can see what the pipes look like without the baffle. (Please note: I still have to clean and restore the pipes!)

UPDATE: 13-July-2026: I managed to get off the old original exhausts, they were rusted solid on the H-box and needed some serious heat and WD40 to get them loose again.

The H-box is rusted so I need to find a suitable replacement for that too but for now I can start fabbing up the mounts for the mufflers.

Stay posted the next update will contain the method used to mount the new mufflers.

I expect this to be done somewhere end of July 2026.

As of today August the 28th the mufflers have been finalized, they required some real work to get the baffles out which is the reason it took longer then end of July.

Mufflers also needed a custom bracket to securely mount them to the CX.

The brackets are made from aluminium which I bent according to my own custom template. I then decided to match the level of detail the rest of the build has I would need to polish the brackets to a mirror shine. After this they were ready to mount!

The brackets were bent and also rounded off to give it a more clean look.

I am very content with these mufflers they look and sound amazing and the project was well worth the effort.
