I finally caved in to demand, and installed exhaust baffles in the dual Dragger Mufflers on my wife's pimped out Altima.

It accomplished eliminating the exhaust drone.

Some after market mufflers have a removeable baffle....It's a good option to thionk about.

Add the cackle of CAI at full throttle to the custom exhaust and you have a mean sounding machine.
