Mercedes SLS AMG: Goodness Gracious, Great Headers Of Fire!

That's hot. No, not in the Paris Hilton silly-slang kind o' way. Rather, the headers on this Mercedes SLS AMG V8 during testing are hot in that holy-mother-of god kind o' way.

You seemed to like the slew of shots of the Mercedes SLS AMG's important bits and pieces, so we kinda figured you'd be all over this shot of the big V8 engine undergoing testing — especially when you check out how burning-red-hot those headers are running. We like. It's the perfect engine pr0n for a Friday afternoon.
