What's the estimated cost to complete this sound proofing?

Not that it matters, but any idea how much weight it added to the car?

I have been thinking about the area behind the seats to cut a little road noise on some roads. Looks like this is a good approach.

Nice installation! Did you use more than 1 roll? How about under the mats in the passenger cabin?

I did this project but did not do the sections over the wheels. I assume you removed those arched panels. Any hints on how that is done would be appreciated. I think most of the road noise/tire hum is now coming through those wheel arches. I believe the material helped the road noise some but what I noticed most is that it made the NPP exhaust sound better INSIDE the car. That was a surprise for me.

Side & rear trim panels are simple to remove. I plastered everything including wheel arches. Rattletrap Xtreme...user friendly & does the job.
