I used dyna-mat extreme on the floor & firewall covered by dyna-liner on the floor and extreme-liner on the firewall.

Huge improvement! No more tinny-ness in teh cabin, able to converes at all speeds, etc. If I didn't have those two big webbers out back sucking birds & planes out of teh sky I probabaly wouldn't be able to hear the engine at all.

I used one of the online proce comparisson services like Nextag and was able to get the real Dyna-mat brand for about 50% off MSRP from two vendors. One of teh vendors ended up being Crutchfield, the other was a tuner co. I remembered at the time but do not now. Regardless they were both legit businesses I had heard of in the past, the price was right, and the product as promised.

You'll need some 3M spray adhesive, tube of weatherstrip adhesive, a wooden roller burnishing tool, and a sharp utility knife to do the install. Easy to do, no worries.
