my experiment will be to remove the rear cats, the resonator, and run a single dual inlet/outlet shorty muffer in the area of the resonator, and delete the stock muffler and run another single dual inlet/outlet shorty muffler with the tips welded on to it...looks stock, oh, I forgot, it would be a true dual system as well...hoping to tone it down with the dual muffler set up and still be true dual set up.. Have the parts, just isn't a priority right now...as it net no HP gains to speak of...
