Gutted my cat, deleted my muffler. Noticeable improvement on low end response.. Awesome turbo whistle when you open window as you are driving, especially in town as sound waves bounce back from store fronts. A little bit of a flutter noise at idle. Not any change at all inside cab as far as noise goes. People who drive with me have no idea that I am not running a muffler. Wife made no comment, has no idea what I did.. I had a muffler shop cut me a 3 inch dia. pipe about 24 inches long, and had them flare each end. Slipped it over existing gap where muffler was, and clamped down tight. Will weld it some other time. I am convinced it was worth the effort.
