I was thinking about getting the Powercore IV with the insert, but I called FMF directly and talked to a tech person to find out about the noise levels. He said even with the insert the pipe would be above 96db.
Here in CA that's a bad thing, if you get caught by a ranger it's either a ticket or you get sent home. In WA it might be different, but if noise is a concern, I would call FMF directly and talk to one of their techs.
I ended up getting the FMF "Q".

...This is an EU model so it is probably not relevant to the leaner US model.... MJ 160,PJ 48,PAJ 80,JET needle OBDUQ if its of any use
Ah, but I imported mine from Canada. Its a Canadian/Australian/New Zealand and ZA model. I odnt know if these are the same as Euro. So I didnt have to deal with lots of stuff like the grey wire, throttle stop etc. I will get the quiet core insert ort do whatver it takes to make it reasonable. Max noise in my state is 96, but I like to keep it at 94 and under. Thanks for the replys. Does anyone have a site for the quiet core insert? I couldnt find it for the Powercore IV SA model on any of the webpages I was looking at.

My FMF PC IV S/A has consistently tested at 96 or 97db. It's throaty, but not obnoxious. It was bought in 2002 though, and I think the new ones might be slightly different.
Bones, do you have the quiet insert in it or is this just the Powercore IV SA out of the box?

I have had it apart to repack, is there some obvious way I would be able to tell?

The 4 has an endcap that's held on with allen screws and accepts the quite insert.
102+ w/o insert
~99 Stocker w/o plug
I had to bump my main jet by 2 and move the needle clip, and fuel screw too.
The FMF is much lighter, but maybe only 5-10% more power then stocker with the plug pulled.
