I too hated the yellow halogens in my '13 GT. I bought a $65 set of Hikari LED's from Amazon and installed them. It was worse than the OEM halogens! After a couple of weeks of not seeing, I put $70 Silverstar Gold XTE halogens in. I could see again, but they were still pretty yellow, which didnt match my 6000K fogs. When a bulb finally blew about 7 months later I found some Hella Optilux Extreme White halogen bulbs. These are 100w vs 55w and I cannot praise them enough! These are white enough to match my fogs, and bright enough to see great again! Best of all they are like $25 on Amazon! I've had them in for 3 months now with no issues related to excess heat or anything.
