/itm/?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649Best mod I ever did on my FZ6R.Selling my Two Brothers exhaust with PCV and Autotune. The exhaust alone sells for over $1K new, so this is a great deal.I had this installed on a 2012 FZ6R, it was a great setup, but I am selling the bike. This is much louder than the stock exhaust, but you can buy a db killer if it is too loud. This system also cuts quite a bit of weight compared to the stock exhaust.The Power Commander allows you to adjust the fuel map so that your bike doesn't run too lean with the much freer-flowing TBR exhaust. You can also have multiple fuel maps, some for performance and some for fuel economy.Also included is the AT-200 Autotune module. This uses the O2 sensor (included) to read the air-fuel ratio and adjusts your map accordingly. It is a very cool setup and allows infinite tuning possibilities.Everything you need is included, even the original install instructions. This will fit the FZ-6R from 2.If you live in the Seattle or Portland areas, I will deliver for free!
