Anybody interested in slk55 AMG quad exhaust??

I have changed my OEM SLK55 AMG quad exhaust for KLeemann's one about one half months ago and initially thought of keeping it. But now, I'm thinking of selling them due to shortage of storage spaces. (I am too lazy to carry them over to my friend's place) And it might be useful for many 280 and 350 owners so I was just wondering if anybody would be interested? Please offer me a reasonable price if you are interested. They have only been used for 5500 miles? As of we speak my current milage is only 5700 miles. In perfect condition no dents or anything.
