Take a look in the Vendor display section for Monstaliner! you can also check out my build thread. It will not cut out road noise, I did put in the heavy duty floor liners in the front, easier to take out and clean when they get full of crap, that helped deaden the sound a small amount. Overall very happy and would do it again.
