Noise Dampening

[STANDO]

I'm looking for ideas to lessen the noise from my aftermarket exhaust. The situation arises during highway travel, at about 2700 rpm the drone is almost enough to drown out the stereo. Is this a common problem with the 08 sedans? I'm using Perrin mufflers right now do other brands have less of the problem? How much does the foam used for stereo installs help out?


Thanks in advance for your ideas and experiences.

Hey, once you have done an exhust mod it is hard to get a quite ride at those rpm speeds due to the great boxer engine (and you right at the point where the turbo starts to spin)! What I have done, is put some dynamat around the boot (bottom,top, side walls and lip) and have found this has reduced the noise some what... Now it is time for that subwoofer!

People have reported positive results with some dynamat in the right spots. I'm not sure about the sedan, however.

Aftermarket mufflers are generally louder than stock. There are some that will be much quieter if you want to go that route.
