dynamat

Hey if I put dynamat on the doors only will it affect exhaust noise? I have a prochamber so it's quiet enough as it is, I want better speaker sound but don't want any of the exhaust noise gone.

You might notice a difference but i don't think that much. They say that it reduces road noise but that's if you lay it down under the seats and the whole bottom. I don't know about the doors.

I lined almost all of my trunk with dynamat extreme and it helped a little with the road noise. I noticed that I could hear the radio better and there wasn't the usual road drone from the trunk area after putting it in. Exhaust was a little quieter in the car, but not much.

I used over 40 sq ft of dynamat extreme, inside door panels, the floor, the trunk, under rear seats, and it helped a lot with my exhaust noise. Granted, I still drive a convertible, so all the dynamat in my car was kinda silly, but it still helps when the top is up. In a coupe, the most help with eliminating exhaust noise would probably be to dynamat the floor and the doors.
