I traded my 2010 1400 GTR a few months back for this years ZX14 but before doing that I removed the full 4 into 1 Area p system I ran on the bike since new.
Curiosity got the better of me so I decided to remove the factory exhaust and see if the Area P would fit, as I new the engines are all pretty similar.
Well I was very happy with the outcome, and you would think this was made for the ZX14.
