left with an ugly large vacant gap
under the side panel where the
left muffler used to reside, but
no worries, the FMF single muf-
fler comes with a UFO-made side
panel to replace the stock left
panel. Sweet!
In one fell swoop, you now
have a bike with more bark

at the back and is four pounds
lighter. Yes, four pounds! That's
significant, especially with a bike
that's already the lightest in its
class.

slight horsepower gains from bot-
tom to mid but a significant boost
from mid to top, with max power
peaking at 50.49 horsepower
compared to 49.81 horsepower
with the stock pipe. Max torque
remains virtually the same, as
it pretty much did across the
board, though there was some
minor torque gains from mid to
top.
"Power delivery is definitely

system. "It did sign off just a tad

The FMF exhaust is louder to

pleasing factory race-bike tone,
