There are two Cats at the end of the downpipes (first picture), two additional secondary cats in the middle section (offset cylindrical canisters), a resonator where the two pipes merge into one and then a muffler at the rear. A midpipe from MadDad will eliminate the secondary Cats and rear resonator (it's fairly large) and replace them with two mini resonators. Should bolt right on and give a nice little bump in power and sound.
