dynamat extreme. extreme is much better (IMO) the original. You need a heat gun with original, and it's not as good, especially with high heat areas.

I lined the front door and basically covered the floor. I still plan to do the rear doors (maybe tonight) and the rear 1/4 panels, along with the hatch (which rattles like a mofo).

I noticed a definate improvement in road noise and floor heat. When the engine switches gears, it's hardly noticable and you can bearly hear the locks in the doors anymore.

When it's all said and done, I'll have atleast 40 sq. feet of dmat in the X. I'm putting an 8w7 in the passenger side rear 1/4 panel, so the dmat will be well worth it.
