I have a Fat Cat with the quiet baffle and at highway speeds the wind noise way over powers the exhaust noise, you really should be using ear plugs at highway speeds, and then it doesn't make any differance.

Cant agree more! The radio sounds much better with earplugs on the highway anyways.

I have a FLHX with a wind shield so i don't have issues with wind or the noise that comes from it. I do however have issue with the exhaust at highway speeds. The big bore has a strong rumble to it. I can set off a car alarm real easy.
I've taken apart the exhaust and I do have the honey comb baffle and it's wrapped wityh some kind of fiberglass ans wire. It looks like it will fall apart prety soon so i dont know how well the fiberglass stuffing will work. At the shop where I had the pipes installed he had a set of D&D fatcats also and they were the standard and we couldn't really tell any difference.

I had Samson Rip Saws, basically drag pipes with no baffles on my SE Fat Boy with the 103" engine. They were outrageously loud. I switched to the Fat Cat, for a quieter exhaust. When I switched exhaust I was surprised how loud the Fat Cat was. I'm sure it sounds louder on my 103" then on a 88", but I doubt if you will think it is too quiet.

Update On Louvered Quite Baffles
We had the D&D louvered wrapped quite baffle installed last week. Also a TTS Master tune. I had high numbers on the dyno with the big bore baffles, but the louvered baffles gave me massive lower end with nice top end.

FLHXXHLF,
you say you had good numbers with the BBQ, but then you said you had massive low end numbers with the standard. Do you have numbers for each? I'd really like to see it because I'm indecisive wether to go with BBQ or Standard Quiet Fat Cat

So are you saying that the standard(louvered) quiet baffle out performed the Big Bore quiet baffle on the dyno and through out? Please get back to me on this because I was thinking about going for the Big bore quiet
