Here are pictures of the new EPA compliant Black Cat Mufflers. First pic is the muffler in one piece, the second pic is after baloney cut. You can clearly see the catalyst and the large valence with Free air Resonance buffer surrounding the Cat Array. So.. Yes.. To answer some skeptics, these Black Cats are for real and not just a muffler that is black to make you think it is different. Thanks... Enjoy the ride..
