Has anyone used a combination like this. Does the dynamat work to lessen the noise from a single shot inside the car? I plan on dynamatting the floor in hopes to lessen the amount of drone I hear inside.
It helps a lot for road nois and all but NOTHING will help a single shot.
Exhaust drone was a bit lower but if you do it on a hot weekend in June like I did you won't think removing the interior and then putting it back in was worth it.
