Check out for HIRs: http://store.candlepower.com/9011hir.html
On paper you get 80% output improvement (1875 lumens HIR vs 1006 halogen), but HIDs double or triple (depending on the color temp you chose) the output:
However, as bramfrank put it, Journey's reflectors are not designed for HIDs, so your beam patter will not be perfect. I have HIDs installed, but don't like the pattern, so plan to modify the headlights to fit HIDs.
