HELP - Upgrading my X5

[jtphillips]

I have a 2001 x5 4.4 le mans blue with the $5,000 bmw
ground effects kit. I am looking for the large oval exhausts
found on the 4.6 and 4.8 models, not the entire exhaust system, just the
tips. Also, my drivers side door has a crack on the light burled
wood that runs across it right under the window. Can you help
with that? Let me know if you can get a good price on the 20
inch rims from the 4.6 or 4.8 also! thanks.
