Ah yes, the infamous 9011 bulb. I was involved with GE at the time of the 9011's development. Basically the glass is coated with materials that reflect IR energy back on to the filament raising its operating temperature thus creating more light. At best it is 15% more efficient than the 9005 and the life expectancy is significantly less (due to the added heat stress). Go to your local auto parts store and replace them with 9005's.
Also, using high wattage bulbs is definitely not recommended. Although I'm not intimately familiar with the Viper's wiring, it's not a chance I'm willing to take with my car for the sake a small improvement in light output. As stated by others there is a fire risk over the long run. The wires may survive for a while but IMHO it's a ticking bomb. Sooner or later you will get a short and the rest is up to random chance. (My opinion is based on 15+ years of automotive lighting experience so you can take it for what it's worth.)
Interesting topic. What changes have others made to the lighting systems in their Vipers?
