MagnaFlow Sys C/B Toyota 4-Runner 03

Starting with the 2.5-inch main piping, this Magnaflow cat-back system is built for your 2003-2009 Toyota 4Runner. It's designed to replace your stock exhaust from the catalytic converter back, aiming to give your 4.0L or 4.7L engine a more resonant and powerful sound. The system uses mandrel-bent tubing, which means the pipe's diameter stays consistent throughout the bends, helping to improve exhaust flow compared to crush-bent pipes.

This Street Series system features one straight-through muffler, engineered to provide a moderate exterior sound level and a mild interior sound. It exits on the passenger side, behind the rear tire, with dual 3 x 3.75-inch polished, double-wall, straight-cut, rolled-edge tips, giving your 4Runner a sportier look. Magnaflow uses CNC precision robotic manufacturing for consistent results, and the entire system is constructed from durable, corrosion-resistant stainless steel. This ensures it can stand up to the elements and maintain its appearance over time.

The design process involved extensive 3D scanning of the 4Runner chassis, which Magnaflow states results in a direct-fit installation that you can often handle yourself. This system is backed by Magnaflow's limited lifetime construction warranty and a 1-year limited finish warranty, giving you confidence in your purchase.
