My exhaust is sometimes deafeningly loud. I'd like it to be a little quieter from inside the car. If I put something like Dynamat down in my trunk and underneath my back seat, would that quiet down the external noise making it quieter inside?

Sound deadening would help.  The more you put down, the better.  If you exhaust is that loud though, I would suggest either adding a resonator or changing your muffler.

Yeah, just found that out. I have a resonator. Could I maybe put one before the cat and have two?
