MagnaFlow Sys C/B GM Yukon 8.1L XL

This MagnaFlow Street Series cat-back exhaust system, part number 15716, is built with 4-inch diameter, mandrel-bent stainless steel piping. This larger diameter allows exhaust gases to flow more freely than the stock system, which can help your 8.1L engine breathe better. The system replaces your factory exhaust from the catalytic converter back, aiming to bring out a more aggressive, resonant engine tone that’s noticeable without being overwhelming, with moderate exterior and mild interior sound levels.

Constructed from durable, corrosion-resistant stainless steel, this system is designed for longevity. MagnaFlow uses CNC precision robotic manufacturing techniques to ensure a consistent build and a direct-fit design, meaning it should install onto your 2001-2006 Chevrolet Suburban 2500 or 2001-2006 GMC Yukon XL 2500 without needing extensive modifications. The system exits on the passenger side rear and features 4-inch polished stainless steel tips with an angle-cut rolled edge, giving your SUV a sportier appearance to match its improved sound.

This cat-back system is dyno-proven for performance gains, and MagnaFlow backs it with a 1-year limited finish warranty and a limited lifetime construction warranty. While this system is designed for a direct fit, it's always a good idea to refer to the manufacturer's installation instructions for specific details and any recommended tools or hardware.
