MagnaFlow Sys C/B 03- GM 2500HD 6.0 Dual CCSB

This is the MagnaFlow Street Series Cat-Back Performance Exhaust System for your 2001-2006 GMC Sierra 2500 HD. It's designed to replace your factory exhaust from the catalytic converter back, giving your truck a more aggressive sound and better flow. If you're looking to change the personality of your truck with a signature MagnaFlow sound and a noticeable bump in performance, this system is a solid choice. It's built to bring out the best in your 6.0L engine.

The system features a fast-flowing, mandrel-bent 3-inch main pipe that leads to dual straight-through mufflers. This design is dyno-proven to improve performance. It exits at the rear with a dual split, and the polished 3.5-inch single-wall tips with rolled edges give it a sporty look. You can expect an aggressive exterior sound level, with a moderate interior sound, so it won't be overwhelming on longer drives. The construction uses durable, corrosion-resistant stainless steel, and it's produced with CNC precision robotic manufacturing techniques for a solid build.

MagnaFlow has used extensive 3D scanning during development to ensure this system is a direct-fit, meaning it should install without major modifications. It comes with a 1-year limited finish warranty and a limited lifetime construction warranty from MagnaFlow, giving you peace of mind with your investment.
