Loud exhaust. Dynamat?

[teal99camaro]

I have a 3 inch TSP rumbler with some mufflers at the end of em. Its really loud inside the car. I hate when the car rattles and the change in my cup holder makes noise, it makes the car feel cheap. Would sound deadening the car help with the noise? Would there be a way for me to make the car quiet on the inside?

i did the rear hatch area, it helped cure the drone a good bit.

A nice thick spray of undercoat under the hatch area (on the undercarriage not inside the car) helped in conjunction with the dynamat I put in. I have headers, catco 3" catalytic converter, and a Loudmouth cat-back setup and this honestly cut down a LOT on the ear piercing volume but it still drones very loud.

my whole trunk/hatch area is dynomatted and it cuts down a lot on the noise. my exhaust sounds quiet to me and i have headers,high flow cat, and rumbler. its a good thing to do when you have passengers in the car b/c they will complain its too loud.
