Bend: I know from experience that the 06 250F and 06 450F have the same mid-pipe bend and muffler positioning. I'd expect the 07s and 08s are the same bend. The bend is even less of an issue if the muffler canister is strap mounted to the subframe.
Diam: I would expect the 450 header end diam is slightly larger than any 250 (as was the case with the 06s). If the 07 250F slip-on comes with a spacer/sleeve for the join, then I think your chances of fitting it are good to certain (either straight on w/out spacer or get a diff spacer). If his 250 slip-on pipe has no spacer then maybe it will not fit (ie. too small to fit over the header). Get some calipers out and measure things.
