Umm, yeap, that would be the ideal choice, I'm working on it.
Meanwhile, why don't you guys post your own riding and owning experiences for both. What kind of mods you may have done, etc.
As for the double shooter in DB4, yes, they sort of look cool, but then, looks like it's a 2-to-1 pipeline which splits into two only just before the cans, which woud possibly make it more bling-bling with extra weight than the ideal silencer solution.
Or does someone know better? Why the two cans, is it for the looks and possibly exhaust note only, or what's with the double cans?
Oh and btw, is there any 'storage' room under the seat or inside the tail, or is it just a hollow monoposto hump behind the seat? Looks like the answer is pretty clear in the case of DB2, though...
