Isn't 4 to 5 inch stacks plenty for our trucks, or should I just shutup?

dont' get 4", get at least 5". I can hardly hear mine while cruising. Mine are mounted at the first stake hole. They are loud under acceleration only, while cruising, the engine is louder (windows up and down). My old 4" out the back was louder in the cab
