Product Details

This Magnaflow Street Series cat-back exhaust system is made for your 2003-2007 Chevrolet Silverado 1500 or GMC Sierra 1500 with the 4.8L or 5.3L engine. It replaces your stock exhaust from the catalytic converter back, giving your truck a more aggressive exterior sound and a moderate interior tone that really lets you hear the engine's personality. You'll notice a difference in how your truck sounds and feels with this system installed.

Built with durable, corrosion-resistant stainless steel, this system features fast-flowing, mandrel-bent 3-inch main piping. It uses straight-through mufflers to help the engine breathe easier, which can lead to dyno-proven performance gains. The system exits at the rear with a dual split, and it comes with 3.5-inch polished stainless steel tips that have a rolled edge and a clamp-on design. Magnaflow uses CNC precision robotic manufacturing for a consistent build, and extensive 3D scanning during development means this system is designed for a direct fit, making installation more straightforward.

This cat-back system includes everything from the catalytic converter back, including the mufflers and the polished exhaust tips. You'll want to refer to the manufacturer's installation instructions for specific details on mounting and any hardware that might be needed, though it's designed for a straightforward bolt-on process. Magnaflow backs this system with a 1-year limited finish warranty and a limited lifetime construction warranty.
