I got this muffler from a shop who tried to sell me a fake spoon "high flow cat". They included this muffler with it. As you can tell in the pictures it is 18 inches long, 2.5 inches in diameter. Comes with a silencer althought I have no idea how it sounds because it has just sat inside my closet. This has never been used. Has a carbon fiber tip which is probably not even carbon fiber. I take accept paypal. Please feel free to pm me or im me on AIM at jchrm80. Thanks for looking. Asking around $25 plus shipping.
