I have AAM short tails got them of Z1performance, but you could order them directly from AAM. They have the option of resonated and non resonated with polished or titanium tips. They are 14-17 pounds lighter then stock, slight drone at certain rpm but sound awesome over all. You also have the option with them of getting an AAM mid pipes at a later stage and making it a cat back. There's plenty of YouTube videos if you want to hear what they sound like, the unresonated ones are a pretty loud setup.
