there is no difference between a b2200 and a b2600 hood. The difference is the hoods on the fuel injected models(b2200i and b2600i). They have a bubble. That's it. The bubble is aesthetic and serves no purpose.
i am runnin one on my 22 cuz i am body dropped and it alows me to clear the motor wit the hood closed....if i didnt have this i would have to cut out the inner webbing structure on the stock hood.
