Different, better, yet not drastically less loud than without them
There is nothing harder than to describe a sound with words.

So I'll start with the conclusion : I love these baffles and my 2015 Road Glide sounds much better with them.

I used the V&H Power Duals header duals and the 4" Blackout Round Slip-on exhausts for a couple of months without them. I liked the sound quite a lot, but it was a bit too loud for me, especially since I live in an urban environment (Paris, France, no less).

I therefore decided to be nice with my neighbors, my wife, my ears and the cops altogether and put these baffles on.

I was quite nervous when I hit the ignition after having installed them (or having them installed, rather, as it is not such a simple task). But I immediately said "perfect" when I heard the sound.

It is definitely quiter at idle and at high revs, but more melodious and more sporty in-between. For example, when you stand still at a red light, the sound is at 5 on a scale of 1 to 10. Give it a quick stroke and all vehicles around you will definitely hear you (7/10).

So, overall, you loose one grade out of ten in dB, but the curve is less linear, the sound less agressive and the result more pleasant to the hear & feel of it all.

So there.

So very hard to install the quiet baffles........
So you're buying the Twin slash exhaust and you think "I should add the quiet baffles" That's all nice, and they do sound good. Once you actually get them installed. That's the difficult part. The installing part. First of all, you need to pull the existing baffles out of the twin slash, so that you can add these quiet baffles. Except there is no easy way. You'll need a slide hammer and an abundance of persistence. Those existing baffles are stuck solid in the exhaust. I ended up drilling a small hole on the underside of the existing baffle where it wouldn't show, and then I put a bolt through it to give my slide hammer something to hold onto. Once the bolt was there I was able to use the slide hammer and whack the baffle out fairly easily. I still had to file the quiet baffle down a little bit to get it to slide into the existing baffle, and then reassemble the whole thing. I spent many hours fighting these quiet baffles. Sweet Moses these things are difficult to install. Just be warned.

Quiet baffle not so quiet.
I installed these baffles on the twin slash rounds and did not notice much a difference. So I ended up wrapping the stock baffles with a fiberglass mesh.

Does the baffle come with all the necessary mounting hardware?
A shopper on May 30, 2014
BEST ANSWER: Yes it does. If I recall, it only requires one bolt and install is very straightforward.
