differences

Which one is better - the Akrapovic titanium with the mt-07 logo engraved, or the one with the yellow/red akrapovic logo. Are there any differences ? Thanks.

Hello guys and gals, Can anyone explain to me the differences on the new model? I know about the new colour schemes and a few minor cosmetic adjustments but wondered what the new 'flat' seat is like. Also heard they made changes to the engine?! If so how does it behave? I'm about to buy one...
