PERFORMANCE
GYTR ® FULL EXHAUST SYSTEMS FOR
YFZ450
This full system was developed for the Factory Yamaha
YFZ450 racers like Bill Ballance and Pat Brown. Power
delivery is strong and smooth with exceptional over-rev
characteristics that make it pull harder and longer in
the upper power range. This full system makes it easy
to put in hard laps for an entire moto or a long off-road
race. Recommended for use with GYTR Jet Kit, High
Flow Air Filter, Billet Air Filter Adaptor Plate, and
Performance CDI.
Features include:
® 102 dBA requirements
