I just bought a 10 sq ft off ebay for $20 its not dyna mat but the off brand hope it works!!!! Noise killers is the company

 

It makes a difference, but not huge. As mentioned already, it helps with the bass, removes some of the audio vibration of the batwing, and helps redirect more sound back out the speaker port. Is it worth it? If you are an audiophile, in which you want to do every possible thing...yes...because you can tell a difference. If you are a average music listener, probably not.

I have it on my Ultra...and I like to think I'm an audiophile...and I noticed a difference, but I know what to listen for when comparing sound from 20 minutes ago when it wasn't there, and 20 minutes later when it was installed.

 

another option is the spray on variety. "Quiet Kote" VB-1S Pro from Cascade Audio Engineering works well. The 18 oz. can will do 2-3 fairings. I get it from Parts Express but I'm sure there's plenty of other sources.

I installed it on the inside of my outer Dead Center Fairing. Can't say there's a huge difference but I thought it was crisper, and a littler clearer on the bass. Not nearly as much as I had originally expected. But better than original.

 

i did big change bought some from ebay

 

I have it, and for the $ it's a noce upgrade. It can't hurt.

 

I used about 4 square feet on the inside of my outer fairing: Brought out the mid-range... It was worth it!!!

 

Are you guys lining the whole inside of your batwing or just the sides by the speakers? I have my fairing out and was thinking of doing the whole thing and then adding the dynaxorb squares right behind the speakers (on top of the dynamat).

 

I'm VERY happy I had my RG fairing dynamated, definately gave me a deeper sound!

 

I covered as much as I could of the inside of the outer fairing: about 4 square feet...
