I did the "Fat Mat" stuff off ebay, covering the complete floor, hump, firewall, rear wheel well part that is in passenger compartment, and the package tray . . . WOW !!! Can certainly tell the car is quieter inside, and you can barely hear the wonderfull exhaust sound . . . so, I say it is worth the effort to install and the little bit (ok, maybe more than a little) of added weight !!!

I also noticed the heat was way down too !!! I had run the engine without the mat installed and noticed how warm the tranny tunnel got - nothing now with the mat installed !!!

I think for the money, the fat mat stuff, is worth it !! As far as it melting or coming unglued . . . can't say as I have gotten things that warm !!!

Cheers
