Wait til you take delivery before you make a decision.
I was 100% ready to upgrade it. But, once I took delivery and dropped it into first, my reaction was that it sounded perfectly sonorous to me. After tossing it around and tapping into the RPMs, I parked it and took some time to admire the natural lines. I ultimately decided to sacrifice a little power and keep the purity of the design and while I was convinced I would grab the Akra exhaust as a backup for later for when I get bored with the stock hp, every time I ride it, that thought becomes further and further distant.
