TWO BROTHERS 005-1500407V CF CARBON EXHAUST FZ1 FZ-1 06-09

(2006-09) Yamaha FZ1 V.A.L.E.™ Slip-On Exhaust Systems: The '06-09 Yamaha FZ1 is 9 lbs lighter than it's 2005 predecessor and sports a thundering 998cc DOHC 20 valve R1 engine - a street machine that's tough to beat by any standard.

By replacing the OEM exhaust canister and slip tube with a precision built Two Brothers Racing performance slip-on exhaust system you'll cut an additional 11.35 lbs from your bike as well as significantly increasing both horsepower and torque throughout the entire powerband. Check out the dyno chart and see for yourself.
