Muffler noise inside a car..., how to reduce it? Options

[malpaso]

Hi all,
maybe it's an idle talk, but I would like to reduce noise inside a car somehow (made by muffler). Especialy low frequences. Does anybody here experience with this?

Thanks

1. resonator
2. dynomat or other sound deadening material

Bulldog is right about the silencer. Its effective at noise reduction but reduces exhaust flow which is generally bad - especially for FI applications.

I am putting a 36" mid-muffler on my car next week to reduce the noise of my 3" straight through exhaust.

can you get a video of the before and after noise of your exhaust. Like hold a camera 2 meters away from the tip of your exhaust and get us a comparison shot.

I would love to here the difference the mid-muffler makes.
