Harley mufflers!

I got a set of Harley mufflers for CHEAP ($10 each). I haven't checked if they'll fit yet... should any Harley muffler fit?

Anyway... here's a pic of the pair. Are these the slots you told me about Wolfie?



Question: What are these 3 screws for?



My left muffler is crooked thanks to a pick up truck that tried to run over me and my bike to make his left turn. I would also very much like a little more rumble to my bike. Not sure if these will help on that account or not, but at least they're really shiny. The chrome on the heat shields is impeccable.

I might even start cleaning my bike if I can put these on... you think it might be due for a little cleaning?

I put some Hardley Sportsters on mine. A little different than those. Check my profile for some pix.

I would bet that if you could remove those screws, you could grab those baffles and twist them out of there. Looks to me like someone drove a spike down the center of that one. There appears to be a hole in the far part of the pipe. Doesn't look stock, if you know what I mean.

The Sportsters I installed have a tab for hanging. Yours have that slot. You may still be able to rig something to hang it.

Good price on them. They're from a Harley Dyna. The screws are for pulling the baffles out. On the ones I had, those were rivets, so my guess is that the PO did something to them. If they're from a newer model, they may have catalytic converters built in. You can see them if you look down the top. They have the same pipe diameter so they should bolt on. The slots are useful. You can make a bracket out of a piece of flat stock and a 5/16" carriage bolt, washer and nut.

Here's a picture from the other side of the muffler, is this gonna be a problem?



Looks like they used some tube to hammer the baffles out, which caused this damage... Is it enough to mess up gas flow and cause problems?

Here's what I found inside:



I've never opened up mufflers before... does it look normal? I can't see any drill holes or other stuff that looks modified.

I saw some pictures on google and some of these things were wrapped in something (fiberglass?)... so is that what they did? Take out the fiberglass packing?

Should I still bolt these things onto my bike?

The first pic is the catalytic converter which should look the same all the way across. Those 3 circles do look like someone tried to pound holes through it.

The second pic is the baffle and yes there should be some kind of fiberglass batting in there, but it's not necessary. My guess is that the PO took the baffles out to try and remove the cats and didn't succeed.

You should be able to put them on your bike, but I believe that they are more restrictive than our stock mufflers. This is why I sold the ones that I bought and picked up some sportster mufflers instead.

Thanks for the reply. I guess I'll just try them out and see if I like them or not. At $10 each, I could even make a little profit if I don't leave them on the bike.

Finally put them on!



I still need to weld on some kinda hanger, but I started it up and they sound alright. Especially for 20 bucks! They're not loud at all, but have a lower rumble to them, which is just about what I wanted.

I also need to figure out a way to tighten down the heat shields on the back so they don't rattle around... the stock mufflers were a lot thicker on the area that the heat shields tighten at the back.
