Dual exhaust

Would someone explain to me why they think that Suzuki went to a dual exhaust on the '07 1k GSXR?
Is there performance gains?
I would think it would add unwanted weight.
Thanks in advance.

Actually to meet emissions (EU and worldwide standards), keep the noise down but to also prevent hp loss from the "more constricting" system. If I were to buy the 07, I'd swap it out with a full Akropovic or Race Yoshimura system anyways.
