MagnaFlow Sys C/B GM H2 6.0L V8 03 Awd

The MagnaFlow Street Series Cat-Back Performance Exhaust System for your 2003-2006 Hummer H2 starts with fast-flowing, mandrel-bent 2.5-inch main piping. This design is key to unlocking a more resonant and powerful engine tone from your 6.0L V8, along with dyno-proven performance gains. It replaces your stock exhaust from the catalytic converter back, offering a direct-fit installation thanks to extensive 3D scanning during development.

This system features two straight-through mufflers that lead to a dual straight passenger side rear exit. The look is finished off with 4-inch polished, double-wall, angle-cut, rolled-edge tips. You can expect moderate exterior sound levels and mild interior sound, giving your H2 a sporty sound and appearance that stands out. The construction uses durable, corrosion-resistant stainless steel, manufactured with CNC precision robotic techniques for a solid build.

MagnaFlow backs this exhaust system with a 1-year limited finish warranty and a limited lifetime construction warranty. This cat-back system is designed to be installed by the owner, making it an accessible upgrade for your Hummer H2.
