This video shows how I replaced the stock slipon mufflers with Cobra 909s on my
2024 Harley Davidson Tri Glide in my backyard.
There's a comparison at the end.

Tools needed:
A 1/2" wrench and a 9/16" wrench.
A rubber mallet is handy for persuading the old ones off.
I also used an impact gun with a 9/16" socket on one of the clamps, but it's not necessary.

I'm not a trained mechanic, just a guy in his backyard.

Follow the installation instructions and use common sense.

This is an easy swap that anyone should be able to do.

I chose the Cobra 909s after reading reviews and looking at prices. I'm looking for that lower sound without blowing out the windows when I go through town at 4am.

I ordered them from PartsGiant around 5am Monday morning. They were shipped out Monday afternoon and I got them on Tuesday. Shipping was fast and free. This is my first experience with partsgiant and I'm happy. I am not affiliated with partsgiant in any way.

I was going to lift the bike off the ground a few inches (on jack stands) but after I got under it, I decided I didn't need to.

I like the Cobra 909s. I think they look and sound much better.



If you see something I could have done better, leave a comment and let me know.


At around 13:55, are some before and after clips so you can hear the difference. The clips are from 6 ft away, same camera, same remote mic.

You can really hear the difference with earbuds or good speakers.

At around 15:16, I'm going over the mountain at about 55mph. Same camera, same remote mic (clipped on to the license plate) used on both clips.

For the video:
cameras Insta360x3 (mostly)
GoPro Hero 5
an old GoPro style dive light
mic AxcessAbles Lavalier Clip On Microphone from Amazon and the Insta360 mic adapter.
