exhaust baffles
I ended up putting the V&H 3" slash cut on the Fatboy and as a couple commented, louder and a bit sharp. Considering the quiet baffles to take that sharpness out but was wondering. Looking at the pictures of the baffles, they have a fiberglass wrap around the center part. It that the only difference between the standard baffle and the quiet. Is the fiberglass wrap a special fiberglass for exhausts, or would regular insulation type be the same. Is fiberglass the same fiberglass. If so, has anyone wrapped the stock baffles and what were the results?

The V&H pipes come with the standard baffles installed, and if you wanted the quiet baffles (like I did), they come separately and you have to change them out yourself.
So I have both sets.
The standard baffle is basically just a straight through pipe with perforations along the center portion.
I'm not really sure what the point of it is, since it offers no restriction whatsoever, other then the tiny difference in inner diameter.
May as well not even be there. The perforations (which are fairly deep) seem to be there only to disrupt the flow a bit.
The quiet baffle is different with not only the wrap, but one end is plugged with a cap (looks like a freeze plug)...
Here's a better picture of the two together:
Standard baffle on the left, Quiet baffle on the right...

I figured it wouldn't be as easy as getting the old pink stuff that was extra from the garage build. I'll call Fuel Moto in the am and order. I wonder if that extra back pressure of the exhaust diversion will require a new map on the PC V? I'll ask about that too.
Thanks

Yeah, there's more of a physical difference than just the fiberglass wrap.

I put quiet baffles in my V&H Longshots and the standard baffles were easy to get out. Just look for a Allen screw on the inner side of the pipe. To keep wrap material from bunching up, I wrapped some thin wire around it. Anyways, the quiet baffles are only a little quieter than the standard ones. They soften the note at lower RPMs but not much different with heavy acceleration. YMMV

The perforated baffles don't look like much, but they do make quite a difference. The original owner of my bike was running it with no baffles but there were two sets of baffles in the box of take-offs I got with it. The deceleration pop was terrible so I put in the set with the shortest perforated section and the pop disappeared completely. The tone, while not really any quieter, became deeper and much more pleasant.

How long did you run the standard baffle before replacing. Only have about 300 miles, so far and figure not many more before the quiet ones get here. Did you have a problem of the fiberglass bunching up while installing the quiet ones. A couple of posts about that problem. One poster commented that if run a while the stock ones were difficult to get out.

And I didn't install the quiet baffles either, the dealer threw in free installation since I bought the pipes and AC there.
