Mine is quiet with 2 mufflers up front and a long pipe to the right rear corner. Pipe is 2.5 inch diameter. If I ever woke anybody up in a campground they must have been sleeping in the road. Maybe the insides of one or both of your mufflers has corroded away and is not cancelling the sound wave. Headers up front are definitely louder than cast iron manifolds and I also have those courtesy of the P.O.. I also have the fender liners installed. Sitting in the driver's seat I can barely hear the engine running. Engine tuning can make a big difference in the amount of sound emitted from headers, but usually more sound will be accompanied by loss of normal power output and poor fuel economy. If it runs well and smooth I would check/replace the mufflers first,especially since I have the equipment to tackle that job. A resonator is just another muffler and will quiet it more (and eliminate exhaust "crack") but also may cost just as much to procure and get installed as replacing the mufflers. Depends on where and how you shop.
