The MagnaFlow Street Series cat-back exhaust for 2003–2006 Hummer H2 6.0L AWD adds a resonant, powerful engine tone with dyno-proven performance. Mandrel-bent 2.5" main piping and a straight-through muffler deliver a dual straight passenger-side rear exit with 4" polished double-wall rolled-edge tips, producing moderate exterior and mild interior sound. The system is direct-fit via extensive 3D scanning and built with CNC precision manufacturing.
