Equipped with the DBX Performance baffle, these slip-ons enhance the exhaust note while providing a free-flowing path and the ideal back pressure to unlock both horsepower and torque.
These 4.5" slip-on mufflers deliver the signature rumble and are made in the United States, backed by a Forever Warranty to guarantee lasting quality.
Note: all slip-ons do not have holes for the O2 sensors.
