pretty soon here I will be putting a dual exhaust on my Silver Fern 1971 LeSabre. It has a 350-4. I am looking for either total quiet with the most flow, or perhaps one step up above quiet. As awesome as it would sound with a set of Flowmasters, the car is a beautiful 4 door cruiser that just wouldn't sound right being what it is. Any advice/recommendations would be helpful. I would hate to set this car up with new dual exhaust and hate the sound. thanks very much.
