The factory lip is out of production but there were some still for sale on onlinemazdaparts.com not too long ago. Fishdonotbounce is selling a used white painted DG front lip.
I have my old lip from my 2003.5 Titanium. Let me know if you want it and ill check shipping and come up with a much cheaper price. only catch is there is a small crack by the driver side air dam that can be easily fixed.
