MagnaFlow Sys C/B 05 Hummer H3 3.5L

The 2.5-inch main piping on this MagnaFlow cat-back system is mandrel-bent, meaning it maintains a consistent diameter throughout. This design is key to achieving the dyno-proven performance gains and the signature resonant, powerful engine tone that MagnaFlow is known for. It's built specifically for the 2006-2010 Hummer H3 with the 3.5L or 3.7L engine, replacing your stock exhaust from the catalytic converter back.

This system features two straight-through mufflers and exits at the rear with a dual split. The tips are 3.5-inch polished, double-wall, angle-cut, and folded-edge, giving your H3 a sporty look to match its sound. You can expect moderate exterior and mild interior sound levels, adding personality to your Hummer without being overwhelming. MagnaFlow uses CNC precision robotic manufacturing for a direct-fit installation, so you can install it yourself without needing specialized tools or welding.

Constructed from durable, corrosion-resistant stainless steel, this exhaust is built to last. It comes with MagnaFlow's 1-year limited finish warranty and a limited lifetime construction warranty, giving you peace of mind. If you're looking to upgrade your Hummer H3's exhaust for both sound and performance, this MagnaFlow system is a solid option.
