I'm upgrading my headers, exhaust, and intake for my 2010 baby so i won't be needing my stock headers or exhaust...plus i have a k&n drop in filter. only had the car 2.5 months so the headers and exhaust are new. the k&n filter is only a few weeks old. I also have the standard filter i'll give you with it. anyone interested? PM me if you are...a reasonable offer gets em individually or as a package.
