Just wanted to post a quick thumbs up. I installed the FatMat hood liner kit today and it definitely made a small improvement in sound levels. I figured for $49 if it helped at all thats worth it alone, and I'm very satisfied. The stock hood is just bare metal. See my reader's rigs for a few pics of the hood liner install. Two thumbs up on this one, I recommend it. 
Here's the link to the kit I used.
