I am not in the Chicago area, but I do have the up pipe(one from header to turbo) It is used, but it is in good shape. I believe it is 2 1/2" and is mandrel bent so it is a major improvement over the stock piece and it should work with either stock or aftermarket headers. If your friend is interested let him know I would let it go for $40 shipped. I can get pictures if you would like. Thanks Dusty
