I used the same 2 x 7 heat shield on mine.
But I also used the Harley heat shield on the muffler.
The narrow neck at the forward end of that shield covered
the longer length of the 10 degree adapter pipe that my
local muffler shop made. (for $10)
You can see that the end my muffler extends 5 or 6 inches
farther back than apache snow's. I like his better.
My muffler also kicks out at the back further that I would like it.
I think that a 6 or 7 degree bend on the adapter pipe would
correct that.

i ended up buying a pair of mufflers as they were the best ones i could find (very slightly used). i got it to just mate up with the stock bolts and used a can to make a shim. had to procure a 'harley' muffler clamp and i believe i got it snugged up pretty well. someone on here told me that if there are very fine gaps they'll eventually get plugged with soot anyway.

love the sound and the look....but where mine sits it might soot up my brake actuator a bit. i'll have to be mindful to rinse it off periodically.

I think it looks great Todd. I also like the look of the muffler shield. Nice job!!

I have an extra Dyna Muffler and shield if anybody's interested. The muffler's been drilled straight through so I assume its very loud. ... and the heat shield has a couple small dings. But they're free for the shipping.

You can get a freeze plug from an auto supply store and drive it into the muffler to replace the drilled out portion of the baffle.

My muffler was aimed right at my rear brakes too. I put over 20,000 miles with it like that and never had a problem. Just clean it whenever you wash your bike and you should be good to go.

I hope it's OK to a revive year-old post but my question(s) are specific to the topic discussed.

I want to add the Dyna muffler and it sounds like I need:

1. An adapter (angled). Will probably just buy the Ryca shown in the link.
2. Possibly some additional washers/spacers on the frame mounts to get things to line-up properly.
3. Optional heat shield.

Does that sound about right?

I'm thinking I may not need to re-jet since I'm in Denver and our air is already thin so the bikes run a touch rich to start with.

How loud is the Dyna? I really don't want the Harley straight-pipe sound but surely wouldn't mind the bike louder than the current stock whisper. I've listened to a bunch of the YouzTubez but many of those are inside garages so the bikes sound really loud!
I have an aftermarket pipe on my 150cc scooter and my S40 is much quieter than my scooter Roll Eyes

Thanks for all the help. Just bought my bike 2 weeks ago and I have the oil changed, new front brake pads, Raptor on my workbench and seat lift ideas in my head!

The DYNA is not loud - it just sounds more like a motorcycle should. I had one on my bike for a while and I really like it.

Sounds like your parts list is complete, the adapter adds to the price but allows you to mount it easier. Be absolutely certain that you get a real Harley Factory DYNA muffler....and if you are buying one form California be warned it will have a catalytic converter in it. The catalytic muffler runs fine - but tends to blue the chrome at the front of the muffler from the heat. Also be sure that the muffler has not been drilled out - there is supposed to be a metal disc in the center that blocks the flow and makes it flow through small holes drilled in the center tube (baffle)....you should not be able to see straight through the muffler.

Yes. And you'll need a muffler clamp to hold it to the pipe, probably a good sized bolt to hold it to the swing arm, and I'd do the heat shield for $10. Good luck!
