Upgrade
Save your money, if your looking for more pep maybe a new exhaust or some mods to your bike might be another possible solution. I got the full two brothers exhaust set up with juice box. YouTube - FZ6R with Two Brothers Exhaust and Juice Box
I installed the Two Brothers Juicebox and Exhaust on my FZ6R. Right away i noticed the increase in horsepower, sound and torque. People don't belive that its only a 600 but it turns some heads. I recommend it, after too many close calls with the stock exhaust, people say they never heard me coming.
Leo Vance Exhaust
That must be a misprint. The only available exhaust is the Two Brothers Racing and M4 full system Exhaust. "Werkes" makes exhaust tips but they look like crap and they are just for show. Save your money, get the full system. Also i Got the TBR Juicebox as well.
