Yet another newb question for all you pro's out there. I'm about ready to buy a set of slip on's for my '08 Blue Busa. Carbon fiber looks good and all but as we all know it's a hell of a lot more expensive than stainless. Is there any difference in performance/longevity? or is it just cosmetic. I like the carbon fiber look and all, but for the price i may just roll wit hthe stainless and use what i save there for my HIDs. as always your expertise is always much appreciated!
