This car had 14 miles on it, and the owner wanted the sports package bumpers put on the car. This required the installation of the sports muffler. Basically, if anyone needs an OEM muffler for a 1997-2003 540i, just drop me a line at sturmgreif@yahoo.de or reply here. I will take pretty much anything for it, as long as you pay shipping. And yes, I cleaned the cosmolene off of it, so it is all clean and shiny. 
If you want pics, just let me know, and I will email them to you.
