fatmat does make a butyl version, it's a tad thicker and a touch more expensive, it's what i used in my crew. it will help, but for noise you need insulation of some sort. you want a jute pad at the barest, all kinds of diff insulations for vehicles on the market, there is also mass loaded vinyl (this is what i used) and numerous types of sound deadening sprays

Thank you for the insight dieseldawg142! After your reply I started digging and was surprised at how few control mats were actually butyl...I ended up ordering Fatmat's Mega Mat...
I'll detail the installation on my build thread...
