Performance Exhaust for ’03 Hummer

New 3- and 4-inch performance exhaust systems from Dynomax for 2003 Hummer H2 help increase engine efficiency and enhance power output by maximizing exhaust outflow. Each system relies on the proven design of the DynoMax Ultra Flo muffler, with straight-through routing to reduce exhaust backpressure. Continuous roving fiberglass technology also produces an aggressive, unique sound.
