There are some threads regarding the use of dynamat but none of them address my problem. I recently installed a Magnaflow with 2" exhaust pipe from the tip of the cat to the muffler. After watching the vid in this post:

the sound didn't seem unreasonable.
So basically, the exhaust is too loud inside the car and I'm wondering how much some dynamat will help reduce the exhaust noise? And has anyone figured out how much is needed to cover the rear tire/trunk area?
