Dynatech SuperMaxx Off Road Intermediate Tubes for use with SuperMaxx Long Tubes (99-04 Lightning ; Harley Davidson F-150)

These high-flow, merge-style Dynatech SuperMAXX intermediate pipes provide maximum exhaust flow, while their slip-together union allows for an easy installation without welding. They feature a collector/converter connection that uses a self-aligning, sintered-metal donut gasket for a long-lasting, leak-free connection. Dynatech SuperMAXX intermediate pipes are available with or without high-flow, stainless steel catalytic converters for increased horsepower and torque. They have provisions for O2 sensors and are fully OBD-II compatible.
