Dude, a cat-back is just that! It is a replacement of the Silencer and Muffler from the catylitic converter back. The cat.(short) is what helps the fumes from the motor burn off and it is located in the exhaust tube/s under and around the center console area under the car. After the cat. in the piping is a resonator/silencer to help get rid of that honda sound. Then after the small resonator tube is the big "muffler" this will change the entire sound of the exhaust to what ever kind that you want...almost. It looks from the pics like you have no resonator and a glasspack style muffler...prolly really loud huh? Put a resonator tube back in...IMO. Oh and your Muffler is what we call a FART CAN!
