Rockridge, hope it works for you. Generally, I would say it is much better but when you are using power or at WOT, the exhaust sound will still be loud.

NOTE-Be careful that you get the Dynamat or whatever brand you choose for flooring. According to the car stereo guru who just did the speaker upgrade on mine door Dynamat is different from floor Dynamat. Reason? Each are designed do deaden likely frequencies (tire/road noise from floor and wind noise from doors)
