i used an insulation that looks like alluminum foil bubble rap. ithink they use it for stereo systems. anyway i put it behined the seat inthe doors and in the lower trim peices by your feet and you could barely hear the engine or the stacks behined my ears. worked great

 

Daniel - looks like yourself and stackx2 used the same stuff. Where'd you get it? Is this the same type of construction insulation mentioned above?

Would you mind looking at the role you still have and giving me the formal maker & name if its still in the packaging?
