FMF product information

Mike from FMF sent me this info on some of the new FMF products including the new Power Core IV-2 SA (Spart Arrester). I'm not sure who performed the tests but it is certainly interesting. The test was done on a YZ426.

----------------------------------------------------------------

Power Core IV-2 Spart Arrestor Part # Y-421 $289.99

Exhaust note is quieter than stock. You can tell immediately even though it's fully forestry legal that there is a huge and very rideable performance for the YZ 426. Performance is focused towards improved bottom to mid-range power designed for the off-roader. The majority of the power increase was distributed through the lower to mid sections of the power band, while still improving the 426's over rev. This new unit has the Power Core IV-2 S/A 3/4 length wing installed and power does not suffer though the DB level was corralled.

Power Core IV-2 Part # Y-420 $269.99

Exhaust note is 2-3 dbs quieter than stock. You can tell immediately that there is a huge and very rideable performance for the YZ 426. The majority of the power increase was designed for the motocrosser, improving bottom end over stock, while focusing most of the power in the mid to top-end regions. This new unit is a straight through design, that is constructed out of FMF's exclusive square core.

Power Bomb Header Part # Y-421H $189.99

The stainless steel Power Bomb unit was originally designed to offset noise penalties associated with a higher flow rear exhaust unit. FMF's Power Bomb knocks 3-5 DB off the meter and makes for a very realistic power gain-mainly bottom to mid range. With the trademarked Power Bomb, FMF realized that the evacuation of sonics gained considerably with the expansion and cooling of exhaust gases into the bomb, then have it recharge to provide a gain in flow characteristics. No loss here, and all gain!

FMF AOF Ignition Part #43-84-02 $399.95

The new AOF Ignition keys in on the TPS (throttle position sensor) and uses the supplied information to select the necessary of three curves available during acceleration. During lower RPM, the AOF ignition will use a curve to improve throttle response and torque. When the throttle is opened up, the AOF will supply a curve to improve mid-range which increase acceleration, and improves top-end in the WOT position. Using the handle bar mounted switch, the rider can select between a top-end "Boost" mode or a torque supplying "Torque" mode. With 2 modes, and three throttle position sensitive curves per each mode, the AOF Ignition will increase power across no matter what the situation.
